[PATCH 08/10] ASoC: SOF: align the hw_free sequence with stop

[Kai Vehmanen <kai.vehmanen@linux.intel.com>]

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Even though the order of stopping the DMA and freeing the widget list is
not important, align the sequence to match with the stop trigger to
avoid confusion.
