Add a new helper print_cache_nexthop replacing print_nexthop which can update the nexthop cache if the process_cache argument is true. It is used when monitoring netlink messages to keep the nexthop cache up to date with nexthop changes happening. For the old callers and anyone who's just dumping nexthops its _nocache version is used which is a wrapper for print_cache_nexthop.
