wasapi: correctly render effects if no custom audio processing is used.

Browse source 
I couldn't find a conceivable use case for calling `new_fluid_audio_driver2`
with `fluid_synth_process` as its callback in client code... So I took the
lazy route.

If custom audio processing is indeed used, nothing would be changed by this
patch. It still gets no effects buffer (like the vast majority of other
drivers).
