Subject: [PATCH] ASoC: soc-pcm: fix up bad merge

A recent change to address pops and clicks with codecs like WSA883X
touched the same code paths as a fix for clearing DAI parameters and
resulted in a bad merge.

Specifically, commit f0220575e65a ("ASoC: soc-dai: add flag to mute and
unmute stream during trigger") made mute at stream close conditional,
while commit 3efcb471f871 ("ASoC: soc-pcm.c: Make sure DAI parameters
cleared if the DAI becomes inactive") moved that same mute call back to
soc_pcm_hw_clean().

Fix up the bad merge by dropping the second mute call from
soc_pcm_clean() and making sure that the call in soc_pcm_hw_clean() is
conditional as intended.

Fixes: bdb7e1922052 ("ASoC: Merge up workaround for CODECs that play noise on stopped stream")
