commit 59abe7bc7e7c70e9066b3e46874d1b7e6a13de14 upstream.
In the case of static pipelines, freeing the widgets in the pipelines that were not suspended after freeing the scheduler widgets results in errors because the secondary cores are powered off when the scheduler widgets are freed. Fix this by tearing down the leftover pipelines before powering off the secondary cores.
