winealsa.drv: Default to Stereo instead of 5.1 Surround.

Some popular ALSA plugins claim support for a large number of channels
because they have the capability to mix that down to the actual hardware
configuration.

Instead of defaulting to 5.1 Surround sound for these plugins, let's
fall back on the much more common Stereo configuration.  Users with
actual 5.1 Surround setups can tell us about it in winecfg.
