xfs: add a XFS_IS_CORRUPT macro
Add a new macro, XFS_IS_CORRUPT, which we will use to integrate some corruption reporting when the corruption test expression is true. This will be used in the next patch to remove the ugly XFS_WANT_CORRUPT* macros. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
