commit 90219f1bd273055f1dc1d7bdc0965755b992c045 upstream.
With IPC3, we reset hw_params during the stop trigger, so we should also
clean up the link DMA during the stop trigger.
Fixes: 1bf83fa6654c ("ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop")
Closes: https://github.com/thesofproject/linux/issues/4455
