netconn_gethostbyname: Fix race reporting success

If the DNS request is dispatched and performed very quickly,
then it can complete before tcpip_callback() actually returns,
in which case we'll destroy the actual err_t error value passed
in the message. Use a local variable for the tcpip_callback
error code so that can't happen.

Resolves #269 https://github.com/espressif/esp-idf/pull/269
