Log message:
Remove dead flag from TCP SYN cache.
The TCP SYN cache timer uses SCF_DEAD flag to detect closed listen
socket. Note that syn_cache_rm() is setting sc_inplisten to NULL
in the same atomic section where SCF_DEAD is set. Also syn_cache_timer()
uses the SYN cache mutex to check sc_inplisten and SCF_DEAD together.
Eliminate SCF_DEAD and rely on existing pointer to listen socket.
