[PATCH v4 0/5] MR310: mf: Fix several reference leaks.

[Rémi Bernon (＠rbernon)]

So that the mf tests pass again on 32bit on the testbot, though they still fail locally with `LIBGL_ALWAYS_SOFTWARE=true GALLIUM_DRIVER=softpipe`.

--
  v4: mf: Uninitialize renderer before creating mixer and presenter.
      mf: Release video renderer services before re-initializing.
      mf: Avoid leaking nodes in IMFTopoLoader_Load.
      mf/tests: Add some missing IMFActivate_Shutdown calls.
      mf/tests: And more consistent reference count checks.
