Subject: [PATCH v3 08/11] drm/vc4: tests: mock: Use a kunit action to
unregister DRM device
The *_mock_device functions allocate a DRM device that needs to be
released using drm_dev_unregister.
Now that we have a kunit release action API, we can switch to it and
don't require any kind of garbage collection from the caller.
