Handle desync: reset timer and refill audio buffer
Handle desync: reset timer and refill audio buffer

Normally `sdl_synchronize` will try to "catch up" if the host time takes
longer than the GB time. But this can introduce latency into the audio
playback. If the host is too far behind, it's better to just reset the
synchronization.
