itojun 809ab7f1ff When listening socket goes away, remove assockated syn cache entires. 
Stale syn cache entries are useless because none of them will be used
if there is no listening socket, as tcp_input looks up listening socket by
in_pcblookup*() before looking into syn cache.

This fixes race condition due to dangling socket pointer from syn cache
entries to listening socket (this was introduced when ipsec is merged in).

This should preserve currently implemented behavior (but not 4.4BSD
behavior prior to syn cache).

Tested in KAME repository before commit, but we'd better run some
regression tests.
