bgpd: Print IPv4 nexthop for IPv6 prefixes under bgp_table_map_apply()

bgpd: Print IPv4 nexthop for IPv6 prefixes under bgp_table_map_apply()

With latest kernels that's possible to have IPv6 routes with IPv4 nexthops.

We already handled this in bgp_zebra_announce():

	nexthop = bgp_path_info_to_ipv6_nexthop(mpinfo_cp,
						&ifindex);

	if (!nexthop)
		nh_updated = update_ipv4nh_for_route_install(
			nh_othervrf,
			nh_othervrf ? info->extra->bgp_orig
				    : bgp,
			&mpinfo_cp->attr->nexthop,
			mpinfo_cp->attr, is_evpn, api_nh);
	else
		nh_updated = update_ipv6nh_for_route_install(
			nh_othervrf,
			nh_othervrf ? info->extra->bgp_orig
				    : bgp,
			nexthop, ifindex, mpinfo, info, is_evpn,
			api_nh);
