Subject[PATCH v2 3/3] drm/vc4: tests: Use KUNIT_DEFINE_ACTION_WRAPPER
From
In order to pass functions to kunit_add_action(), they need to be of the
kunit_action_t type. While casting the function pointer can work, it
will break control-flow integrity.

vc4_mock already defines such a wrapper for drm_dev_unregister(), but it
involves less boilerplate to use the new macro, so replace the manual
implementation.
