ASoC: SOF: ipc4-topology: Protect pipeline free with mutex
When starting/stopping multiple streams in parallel, pipeline triggers and pipeline frees can get interleaved. So use the same mutex used for pipeline trigger to protect the pipeline frees as well. Rename the trigger_mutex to pipeline_state_mutex for more clarity.
