libceph: drop connection refcounting for mon_client
All references to the embedded ceph_connection come from the msgr workqueue, which is drained prior to mon_client destruction. That means we can ignore con refcounting entirely. Signed-off-by: Sage Weil <sage@newdream.net> Reviewed-by: Alex Elder <elder@inktank.com>
