Hal: add voice call usecase to re-select device when SCO ON arrived.

Sometimes routing to bt-sco failed since of the connection status
when setting force use to SCO, but then BT_SCO ON msg arrived, voice
call can't be rerouted.

Add voice call usecase to re-select device when SCO ON arrived to
avoid voice call can't route to right device when SCO state changed.
