net: add missing READ_ONCE(sk->sk_rcvlowat) annotation
In a prior commit, I forgot to change sk_getsockopt() when reading sk->sk_rcvlowat locklessly. Fixes: eac66402d1c3 ("net: annotate sk->sk_rcvlowat lockless reads") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
