This is introducing a load of dead-code again - it should be added when its first used.

In this case, you just need `AudioClient3_Vtbl` so that `mmdevapi.dll` compiles.  So you could just add a zero-inited struct (in the appropriate commit).  Leave filling out functions until you move the audio client handling to `mmdevapi`.
