ASoC: SOF: ipc3-topology: Fix multi-core and static pipelines tear down

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.
