fix audio port ID generation for new AudioTrack and AudioRecord

commit 0f4b3c54 introduced a problem in audio port ID generation
by audio policy manager when a new playback or record track
is created: audio flinger was passing a random port ID to
getOutputForAttr and getInputforAttr.
This caused audio policy to confuse several record tracks
and fail to process capture stop properly.

Bug: 72628781
Test: manual camcorder tests
