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.
