tcp: remove unused TCP_SYNQ_INTERVAL definition

Currently TCP_SYNQ_INTERVAL is defined but never used.

According to "git log -S TCP_SYNQ_INTERVAL net-next/main" it seems
the last references to TCP_SYNQ_INTERVAL were removed by 2015
commit fa76ce7328b2 ("inet: get rid of central tcp/dccp listener timer")
