GFS2: Add get_xquota support
This adds support for viewing the current GFS2 quota settings via the XFS quota API. The setting of quotas will be addressed in a later patch. Fields which are not supported here are left set to zero. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> Reviewed-by: Bob Peterson <rpeterso@redhat.com>
