Eric Dumazet c959387d04 tcp: fix race in tcp_v6_syn_recv_sock()
[ Upstream commit d37fe4255abe8e7b419b90c5847e8ec2b8debb08 ]

tcp_v6_syn_recv_sock() calls ip6_dst_store() before
inet_sk(newsk)->pinet6 has been set up.

This means ip6_dst_store() writes over the parent (listener)
np->dst_cookie.

This is racy because multiple threads could share the same
parent and their final np->dst_cookie could be wrong.

Move ip6_dst_store() call after inet_sk(newsk)->pinet6
has been changed and after the copy of parent ipv6_pinfo.

Fixes: e994b2f0fb92 ("tcp: do not lock listener to process SYN packets")
