ASoC: dapm: Fix locking during codec shutdown

Browse source

commit 01005a729a upstream.

Codec shutdown performs a DAPM power sequence that might cause conflicts
and/or race conditions if another stream power event is running simultaneously.
Use card's dapm mutex to protect any potential race condition between them.
