tcp: initialize variable ecn_ok in syncookies path
[ Upstream commit f0e3d0689da401f7d1981c2777a714ba295ea5ff ]
Using a gcc 4.4.3, warnings are emitted for a possibly uninitialized use
of ecn_ok.
This can happen if cookie_check_timestamp() returns due to not having
seen a timestamp. Defaulting to ecn off seems like a reasonable thing
to do in this case, so initialized ecn_ok to false.
