net: annotate data-races around sk->sk_{rcv|snd}timeo
sk_getsockopt() runs without locks, we must add annotations to sk->sk_rcvtimeo and sk->sk_sndtimeo. In the future we might allow fetching these fields before we lock the socket in TCP fast path. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
