From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
xfs_iget can return -ENOENT for a file that the inobt thinks is
allocated but has zeroed mode. This currently causes scrub to exit
with an operational error instead of flagging this as a corruption. The
end result is that scrub mistakenly reports the ENOENT to the user
instead of "directory parent pointer corrupt" like we do for EINVAL.
Fixes: 5927268f5a04 ("xfs: flag inode corruption if parent ptr doesn't get us a real inode")
