Subject: res_sorcery_realtime.c: Fix crash from NULL sorcery object type.
X-Git-Tag: 13.7.0-rc1~53^2

res_sorcery_realtime.c: Fix crash from NULL sorcery object type.

If the sorcery object type is not found a NULL is returned.
Unfortunately, sorcery_realtime_filter_objectset() will crash after
complaining about not finding the object type and saying to expect errors.

* Use ao2_cleanup() instead of ao2_ref() to prevent the crash.
