[PATCH 0/1] MR8462: mfmediaengine: Delay old presentation clearing until new toplogy was set.

[Bernhard Kölbl (＠besentv)]

Shutting down the media source, while it is still in an active topology, causes Windows' media session to fully shut down. To avoid this, only clear the old presentation on release, shutdown or when a new topology was successfully set.

(FWIW: This solution is definitely not the greatest)
