hal: route use cases properly to SCO device when it arrives

When ever BT_SCO=ON arrives, make sure to route
all use cases to SCO device, otherwise due to delay
in BT_SCO=ON and lack of synchronization for create audio patch
request for SCO device, some times use case not routed properly to
SCO device during VOIP call
