Subject: [PATCH] tcp: Remove unused tw_cookie_values from tcp_timewait_sock
tw_cookie_values is never used in the TCP-stack.
It was added by 435cf559f (TCPCT part 1d: define TCP cookie option,
extend existing struct's), but already at that time it was not used at
all, nor mentioned in the commit-message.
