xfs: Remove XFS_MOUNT_RETERR
XFS_MOUNT_RETERR is going to be set at xfs_parseargs() if mp->m_dalign is enabled, so any time we enter "if (mp->m_dalign)" branch in xfs_update_alignment(), XFS_MOUNT_RETERR is set and so we always be emitting a warning and returning an error. Hence, we can remove it and get rid of a couple of redundant check up against it at xfs_upate_alignment(). Thanks Dave Chinner for the suggestions of simplify the code in xfs_parseargs().
