New Revision: 410011

Log:
Don't attempt to link in an aggregate MWI subscription if an endpoint does not aggregate MWI.

Attempting to link a NULL object into an ao2 container had been benign previously, but since
enabling DO_CRASH in the testsuite, this is now causing a crash. It's better to be right
here anyway.
