FMRadio: Immediately mute AudioTrack once stopRender is called
* This is kind of a hack, to squelch any possible output from when
stopRender is called to when AudioTrack.stop is called. This is
because the render thread may be playing audio and not respond
immediately to a stopRender call, resulting in garbage being written
to the output once the FM input is shut down. (such as in the case of
the headphone/antenna being removed).
