[PATCH 1/4] quartz/vmr9: Do not clear the previous allocator and presenter in IVMRFilterConfig9::SetRenderingMode().

[Zebediah Figura]

From: Zebediah Figura

There cannot be any previous allocator and presenter. They can only be set by
this function, which cannot be called more than once, or by
IVMRSurfaceAllocatorNotify9::AdviseSurfaceAllocator(), which can only be called
after setting the rendering mode.
