ipv6: syncookies: do not skip ->iif initialization
When syncookies are in effect, req->iif is left uninitialized. In case of e.g. link-local addresses the route lookup then fails and no syn-ack is sent. Rearrange things so ->iif is also initialized in the syncookie case. want_cookie can only be true when the isn was zero, thus move the want_cookie check into the "!isn" branch.
