ipv6: NULL pointer dereferrence in tcp_v6_send_ack
The following actions are possible:
tcp_v6_rcv
skb->dev = NULL;
tcp_v6_do_rcv
tcp_v6_hnd_req
tcp_check_req
req->rsk_ops->send_ack == tcp_v6_send_ack
So, skb->dev can be NULL in tcp_v6_send_ack. We must obtain namespace
from dst entry.
Thanks to Vitaliy Gusev <vgusev@openvz.org> for initial problem finding
in IPv4 code.
