mfreadwrite: Store result of object activation in stream transform.

In source_reader_create_transform(), store the result of
IMFActivate_ActivateObject() so that in the event of failure, resources
are freed and an appropriate HRESULT is returned.

Previously, if every object's activation failed, the last part of the
function was not aware of this.
