Reset audio port generation when having recording callback event.

In RecordingActivityMonitor, compare audio device type and address to
know if legacy remote submix is active, which requires querying audio
patches. When there is a recording callback event, the audio patches in
AudioManager may not be up to date. In that case, when getting a
recording callback event, reset audio port generation if the patch
handle is not found in the cached audio patches.
