rG4e19e0d92ac6: Use light-weight versions of routing lookup functions in ng_netflow.
Summary

Use recently-added combination of fib[46]_lookup_rt() which returns rtentry & raw nexthop with
rt_get_inet[6]_plen() which returns address/prefix length of prefix inside rt instead of rib_lookup_info().

New calls does not require reference counting objects and reduce the amount of copied/processed rtentry data.
