net: add missing data-race annotation for sk_ll_usec
In a prior commit I forgot that sk_getsockopt() reads sk->sk_ll_usec without holding a lock. Fixes: 0dbffbb5335a ("net: annotate data race around sk_ll_usec") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
