Fix installation of IPv6 host route to VPN server when using iservice.
The "prepare IPv6 route message to interactive service" was properly
handing the correct interface index (r->adapter_index) for this case,
but then always overwrote the gateway address with our magic tun/tap
fe80::8 value. Only do this for "on tap adapter" routes.
