xfs: Introduce XFS_PTAG_VERIFIER_ERROR panic mask
Currently we have a few PTAGs in place allowing us to transform a filesystem error in a BUG() call. However, we don't have a panic tag for corrupt metadata, so introduce XFS_PTAG_VERIFIER_ERROR so that the administrator can use the fs.xfs.panic_mask sysctl knob to convert any error detected by buffer verifiers into a kernel panic.
