staging: vc04_services: vchiq_core: Log through struct vchiq_instance

Browse source

[ Upstream commit f9c4289883 ]

The handle_to_service() helper can return NULL, so `service` pointer
can indeed be set to NULL. So, do not log through service pointer
(which can cause NULL-deference), instead, use the vchiq_instance
function argument to get access to the struct device.
