Dmitry Monakhov 1e381f60da ext4: do not allow journal_opts for fs w/o journal 
It is appeared that we can pass journal related mount options and such options
be shown in /proc/mounts

Example:
#mkfs.ext4 -F /dev/vdb
#tune2fs -O ^has_journal /dev/vdb
#mount /dev/vdb /mnt/  -ocommit=20,journal_async_commit
#cat /proc/mounts  | grep /mnt
 /dev/vdb /mnt ext4 rw,relatime,journal_checksum,journal_async_commit,commit=20,data=ordered 0 0

But options:"journal_checksum,journal_async_commit,commit=20,data=ordered" has
nothing with reality because there is no journal at all.

This patch disallow following options for journalless configurations:
 - journal_checksum
 - journal_async_commit
 - commit=%ld
 - data={writeback,ordered,journal}
