tcp: tracepoint: only call trace_tcp_send_reset with full socket
tracepoint tcp_send_reset requires a full socket to work. However, it
may be called when in TCP_TIME_WAIT:
case TCP_TW_RST:
tcp_v6_send_reset(sk, skb);
inet_twsk_deschedule_put(inet_twsk(sk));
goto discard_it;
To avoid this problem, this patch checks the socket with sk_fullsock()
before calling trace_tcp_send_reset().
Fixes: c24b14c46bb8 ("tcp: add tracepoint trace_tcp_send_reset")
