tcp: update the netstamp_needed counter when cloning sockets
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
