ASoC: SOF: Intel: hda-dai: add error checks to prevent static analysis warnings

make KCFLAGS='-fanalyzer' sound/soc/sof/intel/ reports several NULL
pointer dereference paths.

Example log:
ops = hda_dai_get_ops(substream, cpu_dai);
  |      |                          ^~~~~
  |      |                          |
  |      |               (14) return of NULL to ‘non_hda_dai_hw_params’ from ‘hda_dai_get_ops’
  |  353 |         sdev = widget_to_sdev(w);
  |  354 |         hext_stream = ops->get_hext_stream(sdev, cpu_dai, substream);
  |      |                       ~~~~~~~~~~~~~~~~~~~~
  |      |                          |
  |      |                          (15) dereference of NULL ‘ops’

The function hda_dai_get_ops() can return NULL, but the return value
is not checked across the board. It's not a problem today, since we do
check in the first use of the function, but static analysis tools are
not aware of the different ALSA stages. Rather than argue forever,
let's just add the error checks consistently and make sure this tool
can be added to the CI checks.
