ASoC: SOF: Intel: hda: fix null deref on system suspend entry
When system enters suspend with an active stream, SOF core
calls hw_params_upon_resume(). On Intel platforms with HDA DMA used
to manage the link DMA, this leads to call chain of

   hda_dsp_set_hw_params_upon_resume()
 -> hda_dsp_dais_suspend()
 -> hda_dai_suspend()
 -> hda_ipc4_post_trigger()

A bug is hit in hda_dai_suspend() as hda_link_dma_cleanup() is run first,
which clears hext_stream->link_substream, and then hda_ipc4_post_trigger()
is called with a NULL snd_pcm_substream pointer.
