[PATCH v4 4/6] quartz/vmr9: Cache surfaces on connection.

[Zebediah Figura]

How to Survive does not reference the IDirect3DSurface9 in
IVMRSurfaceAllocator9::GetSurface(), nor does it dereference it in
IVMRSurfaceAllocator9::TerminateDevice(). Native quartz only asks for each
surface once, when connecting, and releases those surfaces when disconnecting,
which lets these two application bugs cancel each other out.
