tcp: Fix IPv6 fallout from 'Port redirection support for TCP'

'tcp: Port redirection support for TCP' (a3116ac5) added a new member
to inet_request_sock() which inet_csk_clone() makes use of but failed
to add proper initialization to the IPv6 syncookie code and missed a
couple of places where the new member should be used instead of
inet_sk(sk)->sport.
