snd: fix playback from physical cd's and put it in its own proc this is how playback from cd's is supposed to work, reading from the cd without waiting for the rest of the code and mixing it with the sound effects, and it also drastically improves performance. the rest of the program shouldn't have to wait for the cd drive, and it's fine to leave mixing to mixfs rather than having to sync and mix things ourselves (ioproc or otherwise).
