ext4: find old entry again if failed to rename whiteout
commit b7ff91fd030dc9d72ed91b1aab36e445a003af4f upstream.
If we failed to add new entry on rename whiteout, we cannot reset the
old->de entry directly, because the old->de could have moved from under
us during make indexed dir. So find the old entry again before reset is
needed, otherwise it may corrupt the filesystem as below.
/dev/sda: Entry '00000001' in ??? (12) has deleted/unused inode 15. CLEARED.
/dev/sda: Unattached inode 75
/dev/sda: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
Fixes: 6b4b8e6b4ad ("ext4: fix bug for rename with RENAME_WHITEOUT")
