When stressing xfs/083, I found it sometimes fails as the following:
+++ touch 50000 files
setfattr: /home/fsgqa/scratchmnt/INOBT/20627: Operation not permitted
./common/fuzzy: line 18: /home/fsgqa/scratchmnt/INOBT/20627: Operation not permitted
mv: cannot move '/home/fsgqa/scratchmnt/INOBT/20627' to '/home/fsgqa/scratchmnt/INOBT/20627.longer': Operation not permitted
...
xfs_repair did not fix everything
It's simply that INOBT/20627 was an immutable file generated from
fuzzing. Therefore, this patch tries to clear the flag first before
modification. Note that it clears dax flag as well since it prevents
immutable flag from clearing.
