zebra: Fix _route_entry_dump to handle nexthop family as appropriate

Browse Source 
The _route_entry_dump function was not handling the nexthop as passed
in from an upper level protocol appropriate and as such not displaying
the v4/v6 nexthop right in the case where we have both going.

Additionally dump the nexthop vrf as well.
