device-port: moving streams due to changing the status of active_port

Browse source 
When the active port of a sink becomes unavailable, all streams from
that sink should be moved to the default sink.

When the active port of a sink changes state from unavailable, all
streams that have their preferred_sink set to this sink should be moved
to this sink.
