ceph: close out mds, osd connections before stopping auth
The auth module (part of the mon_client) is needed to free any ceph_authorizer(s) used by the mds and osd connections. Flush the msgr workqueue before stopping monc to ensure that the destroy_authorizer auth op is available when those connections are closed out. Signed-off-by: Sage Weil <sage@newdream.net>
