ASoC: SOF: pm: Always tear down pipelines before DSP suspend

When the DSP is suspended while the firmware is in the crashed state, we
skip tearing down the pipelines. This means that the widget reference
counts will not get to reset to 0 before suspend. This will lead to
errors with resuming audio after system resume. To fix this, invoke the
tear_down_all_pipelines op before skipping to DSP suspend.
