FM-TOWNS AUDIO: fix thread lockups and cleanup

- fixed lockup situation in imuse destructor (only concerning the fm-towns driver)
- fixed lockup situation when AudioCDManager functions get called
(in both cases both the main thread and the mixer thread would get locked in different mutex belonging to the other thread)
