During XRUN recover process (in pipeline_xrun_recover() function), "COMP_TRIGGER_XRUN" command will be processed first, then "COMP_TRIGGER_START" command will be processed. If the host dma is not stopped in the first command process, we will hit "eS0" error in the hda_dma_start() function during "COMP_TRIGGER_START" command process. The XRUN recover process will fail.
