ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop

Browse Source 
In the case of repeated start/stop without involving hw_free, the stream
tag needs to be preserved for the subsequent starts. So, skip performing
the DMA clean up during stop and handle it only during suspend or
hw_free.
