xfrm: esp6: fix the location of the transport header with encapsulation
commit 17175d1a27c6 ("xfrm: esp6: fix encapsulation header offset
computation") changed esp6_input_done2 to correctly find the size of
the IPv6 header that precedes the TCP/UDP encapsulation header, but
didn't adjust the final call to skb_set_transport_header, which I
assumed was correct in using skb_network_header_len.
Xiumei Mu reported that when we create xfrm states that include port
numbers in the selector, traffic from the user sockets is dropped. It
turns out that we get a state mismatch in __xfrm_policy_check, because
we end up trying to compare the encapsulation header's ports with the
selector that's based on user traffic ports.
Fixes: 0146dca70b87 ("xfrm: add support for UDPv6 encapsulation of ESP")
Fixes: 26333c37fc28 ("xfrm: add IPv6 support for espintcp")
