When selinux/encryption is enabled, xattr entry node is added into TNC
before host inode when creating new file. So it is possible to find
xattr entry without host inode from TNC. Orphan debug checking is called
by ubifs_orphan_end_commit(), at that time, the commit semaphore is
already unlock, so the new creation won't be blocked.

The tmpfile could be added into orphan list twice, first time is
creation, the second time is removing after it is linked. The orphan
entry could be added twice for tmpfile if following sequence is
satisfied:
ubifs_tmpfile
ubifs_jnl_update
ubifs_add_orphan // first time to add orphan entry
P1 P2
ubifs_link do_commit
ubifs_orphan_start_commit
orphan->cmt = 1

ubifs_err(c, "orphaned twice")
return -EINVAL // unlink failed!
ubifs_orphan_end_commit

Fix it by removing orphan entry from orphan tree in advance, rather than
remove it from orphan tree in committing process.

UBIFS will do commit at the end of mounting process(rw mode), dead
orphans(added by insert_dead_orphan in replaying orphan) are deleted
by ubifs_orphan_end_commit(). The only reason why dead orphans are
added into orphan list is that old orpans may be lost when powercut
happens in ubifs_orphan_end_commit():
ubifs_orphan_end_commit // TNC(updated by orphans) is not written yet
if (c->cmt_orphans != 0)
commit_orphans
consolidate // traverse orphan list
write_orph_nodes // rewrite all orphans by ubifs_leb_change
// If dead orphans are not in list, they will be lost when powercut
// happens, then TNC won't be updated by old orphans in next mounting.
Luckily, the condition 'c->cmt_orphans != 0' will never be true in
mounting process, there can't be new orphans added into orphan list
before mounting returned, but commit will be done at the end of mounting.

Now, the entire inode with its' xattrs are removed while replaying
orphan nodes. There is no need to add xattr inodes into orphan area,
which is based on the fact that xattr entries won't be cleared from
disk before deleting xattr inodes, in another words, current logic
can make sure that xattr inode be deleted in any cases even UBIFS not
record xattr inode into orphan area.
Let's looking for possible paths that could clear xattr entries from
disk but leave the xattr inode on TNC:
1. unlink/tmpfile -> ubifs_jnl_update: inode(nlink=0) is written
into bud LEB and added into orphan list, then:
a. powercut: ubifs_tnc_remove_ino(xattr entry/inode can be found
from TNC and being deleted) is invoked in replaying journal.
b. commit + powercut: inode is written into orphan area, and
ubifs_tnc_remove_ino is invoked in replaying orphan nodes.
c. evicting + powercut: xattr inode(nlink=0) is written on disk,
xattr is removed from TNC, gc could clear xattr entries from
disk. ubifs_tnc_remove_ino will apply on inode and xattr inode
in replaying journal, so lost xattr entries will make no
influence.
d. evicting + commit + powercut: xattr inode/entry are removed from
index tree(on disk) by ubifs_jnl_write_inode, xattr inode is
cleared from orphan area by ubifs_jnl_write_inode + commit.
e. commit + evicting + powercut: inode is written into orphan area,
then equivalent to c.
2. remove xattr -> ubifs_jnl_delete_xattr: xattr entry(inum=0) and
xattr inode(nlink=0) is written into bud LEB, xattr entry/inode are
removed from TNC, then:
a. powercut: gc could clear xattr entries from disk, which won't
affect deleting xattr entry from TNC. ubifs_tnc_remove_ino will
apply on xattr inode in replaying journal, ubifs_tnc_remove_nm
will apply on xattr entry in replaying journal.
b. commit + powercut: xattr entry/inode are removed from index tree
(on disk).
Tracking xattr inode in orphan list is imported by commit 988bec4131
("ubifs: orphan: Handle xattrs like files"), it aims to fix the similar
problem described in commit 7959cf3a75 ("ubifs: journal: Handle
xattrs like files"). Actually, the problem only exist in journal case
but not the orphan case. So, we can remove the orphan tracking for xattr
inodes.

When powercut happens after deleting file, the xattr inode could be
alone existing in TNC but its' xattr entry cannot be found in TNC.
File inode and xattr inode are added into orphan list after deleting
file, file inode's nlink is 0 but xattr inode's nlink is not 0 (PS:
zero nlink xattr inode is written on disk in evicting process by
ubifs_jnl_write_inode). So, following process could happen:
1. touch file
2. setxattr(file)
3. unlink file
// inode(nlink=0), xattr inode(nlink=1) are added into orphan list
4. commit
// write inode inum and xattr inum into orphan area
5. powercut
6. mount
do_kill_orphans
// inode(nlink=0) is deleted from TNC by ubifs_tnc_remove_range,
// xattr entry is deleted too.
// xattr inode(nlink=1) is not deleted from TNC
Finally we could see following error while debugging UBIFS:
UBIFS error (ubi0:0 pid 1093): dbg_check_filesystem [ubifs]: inode 66
nlink is 1, but calculated nlink is 0
UBIFS (ubi0:0): dump of the inode 66 sitting in LEB 12:2128

nlink 1

xattr_size 0

Fix it by removing entire inode with it's xattrs while replaying orphan,
just replace function ubifs_tnc_remove_range by ubifs_tnc_remove_ino.
