hal: route to speaker, when USB HS is unplugged
When USB headset is disconnected the music playback paused
and the policy manager send routing=0. If USB headset is
connected before the standby time, AFE is not closed and opened,
so routing to speker will guarantee AFE reconfiguration and
AFE will be opend once USB is connected again, within standby
time.
