Issue: MDNS server initially sends probing packets to resolve naming confilicts with already registered service instances. In case of a conflict, instance name is altered and probing restarts. Original instance however wasnnot removed from the structure and upon service removal only one entry was removed and a dangling service might have been kept in the structure to bring about a crash. Resolution: Keep only one instance of a service in the probing structure. Closes IDF-498 * Original commit: espressif/esp-idf@265e983a45
