[radsecproxy] duplicate dynamic discovery

Symptom: radsecproxy is sometimes doing a dynamic discovery (and opens a new tls connection) even if there already is a working (dynamically discovered) connection for the given realm. Cause: Due to a bug in 'hasdynamicserver()' all information about dynamically discovered realms is removed when any dynamic connection gets closed.
