ipv4: tcp: give socket pointer to control skbs
ip_send_unicast_reply() send orphaned 'control packets'.
These are RST packets and also ACK packets sent from TIME_WAIT.
Some eBPF programs would prefer to have a meaningful skb->sk
pointer as much as possible.
This means that TCP can now attach TIME_WAIT sockets to outgoing
skbs.
