xfs: remove XFS_QMOPT_DQSUSER
Just read the id 0 dquot from disk directly in xfs_qm_init_quotainfo instead of going through dqget and requiring a special flag to not add the dquot to any lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
