AudioService: Go back to virtual SCO calls on multi-function units

Direct raw audio channels to these HFP devices is resulting in
dead audio on hangouts, on all devices. Until that is figured
out and/or fixed, go back to establishing a virtual call to open
up the audio channels

Fix ringer mode being unneededly changed by setting ringer mode volume to 0.

When having set the ringer mode to silent on a device with vibrator and
calling setStreamVolume() for the ringer stream again (e.g. in one of
the volume control dialogs in the settings app), the ringer mode is set
to vibrate, although there's no reason to do so.

Fix that by remembering the last non-normal (that is, either silent or
vibrate) ringer mode and using that when setting the stream volume to 0.
