This moves call to spk_stop_serial_interrupt() function out of synth_release()
and into release() method of specific spk_synth instances. This is because
a TTY-based synth implementation wouldn't need spk_stop_serial_interrupt()
call. Moving it into each synth's release() method gives the decision of
calling spk_stop_serial_interrupt() to that synth. TTY-based synths which
follow in this patchset simply wouldn't call it.
