I fixed this.  Disabling DSP from the UI will also stop its emulation now.
For me the CPU consumption drops from 50% (DSP idling) to 30% when
DSP is disabled. (non-idle DSP causes 60-90% CPU usage.)

Toggling DSP without rebooting the emulation may have strange effects,
so I wonder should we force reboot on DSP emulation change?

PS. Laurent, I commited also couple other trivial cleanup for DSP code.
