ipv6: tcp: add a missing tcp_v6_restore_cb()
Dmitry reported use-after-free in ip6_datagram_recv_specific_ctl()
A similar bug was fixed in commit 8ce48623f0cf ("ipv6: tcp: restore
IP6CB for pktoptions skbs"), but I missed another spot.
tcp_v6_syn_recv_sock() can indeed set np->pktoptions from ireq->pktopts
Fixes: 971f10eca186 ("tcp: better TCP_SKB_CB layout to reduce cache line misses")
