Add nhop parameter to rti_filter callback.

One of the goals of the new routing KPI defined in r359823 is to
 entirely hide`struct rtentry` from the consumers. It will allow to
 improve routing subsystem internals and deliver more features much faster.
This change is one of the ongoing changes to eliminate direct
 struct rtentry field accesses.

Additionally, with the followup multipath changes, single rtentry can point
 to multiple nexthops.

With that in mind, convert rti_filter callback used when traversing the
 routing table to accept pair (rt, nhop) instead of nexthop.
