[XFS] Propagate errors from xfs_trans_commit().
xfs_trans_commit() can return errors when there are problems in the transaction subsystem. They are indicative that the entire transaction may be incomplete, and hence the error should be propagated as there is a good possibility that there is something fatally wrong in the filesystem. Catch and propagate or warn about commit errors in the places where they are currently ignored.
