Antoine Tenart dc6456e938 net: ipv6: fix skb hash for some RST packets
The skb hash comes from sk->sk_txhash when using TCP, except for some
IPv6 RST packets. This is because in tcp_v6_send_reset when not in
TIME_WAIT the hash is taken from sk->sk_hash, while it should come from
sk->sk_txhash as those two hashes are not computed the same way.

Packetdrill script to test the above,

   0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
  +0 fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
  +0 connect(3, ..., ...) = -1 EINPROGRESS (Operation now in progress)

  +0 > (flowlabel 0x1) S 0:0(0) <...>

  // Wrong ack seq, trigger a rst.
  +0 < S. 0:0(0) ack 0 win 4000

  // Check the flowlabel matches prior one from SYN.
  +0 > (flowlabel 0x1) R 0:0(0) <...>
