Eric Dumazet e84a4927a4 net: annotate races around sk->sk_uid 
sk->sk_uid can be read while another thread changes its
value in sockfs_setattr().

Add sk_uid(const struct sock *sk) helper to factorize the needed
READ_ONCE() annotations, and add corresponding WRITE_ONCE()
where needed.

Fixes: 86741ec254 ("net: core: Add a UID field to struct sock.")
