	security: fix remotely triggerable crash in SSL/TLS code
When a server is running with SSL/TLS support compiled in, it is trivial to crash the server by sending an MOTD request via another server in the network. - ONLY servers without ssl/tls support compiled in are not affected. Disabling SSL in the configuration (no ssl listening ports, etc) does NOT help. - servers that are running standalone (i.e., not connected to any other servers) are not affected, either. This affects all ngircd releases since ngircd 13 (earlier versions have no SSL/TLS support).
