Catch up on the CAN driver API argument naming changes: - Unify naming of callback function pointers as "callback". - Unify naming of user-specified callback function arguments as "user_data". - Instances and pointers to struct zcan_frame are named "frame", not "msg", to avoid confusion with the CAN message queue support.
