Eric Dumazet 392096736a ipv6: tcp: fix potential NULL deref in tcp_v6_send_reset() 
syzbot found a crash in tcp_v6_send_reset() caused by my latest
change.

Problem is that if an skb has been queued to socket prequeue,
skb_dst(skb)->dev can not anymore point to the device.

Fortunately in this case the socket pointer is not NULL.

A similar issue has been fixed in commit 0f85feae6b71 ("tcp: fix
more NULL deref after prequeue changes"), I should have known better.

Fixes: 323a53c41292 ("ipv6: tcp: enable flowlabel reflection in some RST packets")
