tcp: update the netstamp_needed counter when cloning sockets

Browse source

This fixes a netstamp_needed accounting issue when the listen socket
has SO_TIMESTAMP set:

    s = socket(AF_INET, SOCK_STREAM, 0);
    setsockopt(s, SOL_SOCKET, SO_TIMESTAMP, 1); -> netstamp_needed = 1
    bind(s, ...);
    listen(s, ...);
    s2 = accept(s, ...); -> netstamp_needed = 1
    close(s2); -> netstamp_needed = 0
    close(s); -> netstamp_needed = -1
