AudioManager: fix device callbacks when native audio server restarts

Fix device comparison when creating the list of added or removed devices
in broadcastDeviceListChange_sync(): compare only type and address as
the port ID changes when the native audio server restarts.

Also reload the device port cache when the native audio server death
notification is received in the AudioPortEventHandler instead of doing
it later n the OnAmPortUpdateListener callback.

This avoids sending spurious audio device removed/added callbacks to
clients.
