audio: clean up before monitor clean up
Since aa5cb7f5e, the chardevs are being cleaned up when leaving qemu,
before the atexit() handlers. audio_cleanup() may use the monitor to
notify of changes. For compatibility reasons, let's clean up audio
before the monitor so it keeps emitting monitor events.
The audio_atexit() function is made idempotent (so it can be called
multiple times), and renamed to audio_cleanup(). Since coreaudio
backend is using a 'isAtexit' code path, change it to check
audio_is_cleaning_up() instead, so the path is taken during normal
exit.
