Fix tls_connection_set_success_data() in TLS library wrappers

Some of the TLS library wrappers defined only an empty function for
tls_connection_set_success_data(). That could result in memory leaks in
TLS server cases, so update these to do the minimal thing and free the
provided buffer as unused.
