xfs will not allow combining other panic masks with
XFS_PTAG_VERIFIER_ERROR.
# sysctl fs.xfs.panic_mask=511
sysctl: setting key "fs.xfs.panic_mask": Invalid argument
fs.xfs.panic_mask = 511
Update to the maximum value that can be set to allow the full range of
masks. Do this using a mask of possible values to prevent this happening
again as suggested by Darrick.
Fixes: d519da41e2 ("xfs: Introduce XFS_PTAG_VERIFIER_ERROR panic mask")
