xfs: add a xfs_dqhold helper
Factor the common pattern of: xfs_dqlock(dqp); XFS_DQHOLD(dqp); xfs_dqunlock(dqp); into a new helper, and remove XFS_DQHOLD now that only one other caller is left. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
