ao_wasapi: exit earlier if there are zero playback devices found

Browse Source 
Previously, if the enumerator found no devices, attempting to get the default
device with IMMDeviceEnumerator::GetDefaultAudioEndpoint would result in the
cryptic (and undocumented) E_PROP_ID_UNSUPPORTED. This way, the user is given a
better indication of what exactly is wrong and isolates any other possible
triggers for this error.
