ASoC: SOF: ipc4-pcm: Do not run the trigger pipelines if no spipe is stored
If the pipeline setup fails at the first widget/pipeline then we will have
no spipe stored under the pipeline_list->pipelines, the
pipeline_list->count is 0.
If this is the case we would have a NULL pointer dereference if the
execution is allowed to proceed.
Check for this condition along with the pipeline_list->pipelines check
