ao_wasapi: actually use hw volume support information for exclusive mode

Browse Source 
Do not try and set/get master volume in exclusive if there is no
hardware support. This would just uselessly change the master slider,
but have no effect on the actual volume.

Furthermore if getting hardware volume support information fails, then assume
it has none.
