GFS2: Hook gfs2_quota_sync into VFS via gfs2_quotactl_ops
The plan is to add further operations to the gfs2_quotactl_ops in future patches. The sync operation is easy, so we start with that one. We plan to use the XFS quota control functions because they more closely match the GFS2 ones. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
