[ Upstream commitfb97bc2e47] The light_up_connector helper function in the HDMI infrastructure unit tests uses drm_atomic_set_crtc_for_connector(), but fails when it returns an error. This function can return EDEADLK though if the sequence needs to be restarted, and WW_MUTEX_SLOWPATH is meant to test that we handle it properly. Let's handle EDEADLK and restart the sequence in our tests as well.
