syncookies: Make sure ECN is disabled
[ Upstream commit 16df845f4566bc252f3e09db12f5c2f22cb44226 ]
ecn_ok is not initialized when a connection is established by cookies.
The cookie syn-ack never sets ECN, so ecn_ok must be set to 0.
Spotted using ns-3/network simulation cradle simulator and valgrind.
