staging: vchiq_core: Pass vchiq_bulk pointer to make_service_callback()

Browse Source 
Pass struct vchiq_bulk pointer to make_service_callback() instead of
just passing the bulk->cb_data. This is a preparatory change when we
need to pass the callback data user pointer (__user) in a subsequent
commit.
