Stops DMA unconditionally on xrun without waiting.
Data flush is not needed as pipeline will go through
prepare and restart anyway. Waiting here during xrun
recovery with multiple tasks running causes interrupt
stack overflow. Waiti instruction lowers irq level to
0, which allows to run multiple scheduled tasks in the
same time on the same irq level and ends in DSP panic.
