[PATCH] xfs: remove old and redundant comment in xfs_mount_validate_sb

[Wang Sheng-Hui]

Per Dave,
The error messages document the reason for the checks better than the comment
and the comments about volume mounts date back to Irix and so aren't relevant
any more. So just remove the old and redundant comment.
