[PATCH 1/2] ASoC: SOF: Intel: hda-dai: Drop misleading comment regarding dma_data

[Peter Ujfalusi]

The comment in hda_link_dma_hw_params() is no longer valid as the dma_data
is set to NULL at system suspend as well.

Instead of rewording the comment to state the obvious: try to take the
hext_stream from the dma_data and if it is not set then assign a new one
and store it as dma_data.
