Bob Peterson b2a846dbef gfs2: Ignore journal log writes for jdata holes 
When flushing out its ail1 list, gfs2_write_jdata_page calls function
__block_write_full_page passing in function gfs2_get_block_noalloc.
But there was a problem when a process wrote to a jdata file, then
truncated it or punched a hole, leaving references to the blocks within
the new hole in its ail list, which are to be written to the journal log.

In writing them to the journal, after calling gfs2_block_map, function
gfs2_get_block_noalloc determined that the (hole-punched) block was not
mapped, so it returned -EIO to generic_writepages, which passed it back
to gfs2_ail1_start_one. This, in turn, performed a withdraw, assuming
there was a real IO error writing to the journal.

This might be a valid error when writing metadata to the journal, but for
journaled data writes, it does not warrant a withdraw.

This patch adds a check to function gfs2_block_map that makes an exception
for journaled data writes that correspond to jdata holes: If the iomap
get function returns a block type of IOMAP_HOLE, it instead returns
-ENODATA which does not cause the withdraw. Other errors are returned as
before.
