ASoC: SOF: remove incorrect clearing of prepared flag
When the system is suspended while a PCM is paused, it doesn't receive
the SUSPEND trigger. So, the SOF driver has to ensure that the PCM and
the widgets associated with the paused PCM are freed in the firmware
during suspend. This is handled in the
sof_tear_down_left_over_pipelines() call. But since the state of this
PCM is SUSPENDED, we end up clearing the prepared flag for the PCM
before freeing it. This results in IPC errors while freeing the widgets.
But because the widget use_counts are reset to 0 even though the IPC
fails, releasing the paused stream after resuming from suspend proceeds
normally.
Fix the IPC errors by removing the clearing of the prepared flag in
sof_set_hw_params_upon_resume(). In fact, we can remove the
sof_set_hw_params_upon_resume() and call
snd_sof_dsp_hw_params_upon_resume() directly. This will ensure that the
PCM is freed in the firmware before the IPC's for freeing the widgets
are sent.
