Eric Dumazet 2ef2b20cf4 net: annotate data-races around sk->sk_{data_ready,write_space} 
skmsg (and probably other layers) are changing these pointers
while other cpus might read them concurrently.

Add corresponding READ_ONCE()/WRITE_ONCE() annotations
for UDP, TCP and AF_UNIX.

Fixes: 604326b41a ("bpf, sockmap: convert to generic sk_msg interface")
