already been cleaned up.  Any router_retry requests must be cancelled

silc_server_create_connections is made.  (This routine is called when

connection auth, the server will corrupt the heap due to not properly

to a remote router server, where both ends of the connection have public
keys configured, but the initiator server's IP is wrong.  In this case,
we will get past key exchange and then fail at the connection auth
packet, typically crashing the initiator silcd after heap corruption.
