xfs: Fix the situation that mount operation rejects corrupted XFS

Browse Source 
On upstream kernel, running some tests which corrupt XFS on purpose
got the mismatched output. e.g. running xfs/087:
------------------------------------------------
 + check fs
 + corrupt image
 + mount image
-+ modify files
-broken: 1
 + repair fs
 + mount image (2)
------------------------------------------------

It is reasonable for corrupted XFS to be caught and rejected by mount
or read/write operation.
