AFAIR dns_gethostbyname uses other tcpip thread only components, so using it from outside this thread can be unsafe. You can however post your callback to be executed on lwip thread - it is usually sufficient (we use similar patter to handle incoming udp data via callback in tcpiip thread instead of blocking with netconn).
