ASoC: pcm: send DAPM_STREAM_STOP event in dpcm_fe_dai_shutdown
A recent change removed the call to send the DAPM_STREAM_STOP
event in dpcm_fe_dai_shutdown. But this causes a regression
when a PCM prepare is not paired with a hw_free. So, add
the DAPM_STREAM_STOP event back to dpcm_fe_dai_shutdown()
to fix this.
The new sequence would be:
soc_pcm_prepare()
-> SND_SOC_DAPM_STREAM_START
soc_pcm_hw_free()
-> soc_pcm_hw_free()
-> SND_SOC_DAPM_STREAM_STOP
dpcm_fe_dai_shutdown()
-> SND_SOC_DAPM_STREAM_STOP
Note that the DAPM_STREAM_STOP will be called twice but it seems
harmless.
