xfs: standardize quota verification function outputs
Rename xfs_dqcheck to xfs_dquot_verify and make it return an
xfs_failaddr_t like every other structure verifier function.
This enables us to check on-disk quotas in the same way that we check
everything else. Callers are now responsible for logging errors, as
XFS_QMOPT_DOWARN goes away.
