[PATCH] winepulse.drv: Add get ISimpleAudioVolume interface by IAudioSessionControl2.

[Andrew Eikum]

Hi Jiajin,

Could you add a test for this in <dlls/mmdevapi/tests/render.c>?

Also, we have several audio drivers in Wine: winealsa, wineandroid,
winecoreaudio, wineoss, and winepulse. The other drivers should be
updated to have this same change.

Thanks,
Andrew
