[PATCH v6 1/2] mf: Clear queued topologies on session shutdown.

[Bernhard Kölbl]

From: Bernhard Kölbl

Programs might expect objects inside the queued toplogy to be freed,
before they eventually call release on the session itself.

This fixes reference leaks to stored objects in queued topology nodes,
even when IMFMediaSession_Shutdown() was called.

I opened !3067, so we can continue discussing this there.
