[PATCH nf v2] ipvs: fix AF assignment in ip_vs_conn_new()

[Michal Kubecek <mkubecek@xxxxxxx>]

If a fwmark is passed to ip_vs_conn_new(), it is passed in
vaddr, not daddr. Therefore we should set AF to AF_UNSPEC in
vaddr assignment (like we do in ip_vs_ct_in_get()), otherwise we
may copy only first 4 bytes of an IPv6 address into cp->daddr.

v2: fix messed up {d,v}addr and p->{d,v}addr, add info about the
outcome (thanks to Julian Anastasov)
