MKE CD-ROM audio and data fixes.

Browse Source 
1. On unknown commands just return a fine data push, fixes the OS/2 built-in MKE cdrom driver being unrecognized.
2. Okay, but I don't know if it's right, but don't play audio on the seek command, fixes actual audio stop when prompted to, (Audio still works fine if you actually want to play from a CD player).
