zebra: fix rtnh_len in the rt_netlink messages for multipath case
In _netlink_route_build_multipath():
- Each time when appending a IPv4 gateway in the message, rtnh_len
is increased by sizeof (struct rtattr) + 4, where we should use
"bytelen" instead of the hard coding "4".
- As what done for IPv4, we should increase rtnh_len accordingly
along with adding a IPv6 gateway, or else the IPv6 gateways will
be lost.
