totem: Use uint64_t type and QB_TIME_NS_IN_MSEC

Function message_handler_orf_token contains extra debug info enabled by
defining GIVEINFO. Insted of using long long unsigned int use better
suited uint64_t and make use of QB_TIME_NS_IN_MSEC constant instead
of hardcoded number. Also compile tv_old conditionally so it is not used
by accident.
