Netconf: Report success, and don't get stuck without a way out

- The result was only ever written on cancel, so a connection that worked
  gave the game back whatever was in the field, which some fill with -1.
- Infrastructure mode drew a Cancel button that did nothing, so if the
  access point never gave an IP there was no way out. Cancelling now also
  disconnects the connect it started, so the game isn't left connected
  after being told the dialog was aborted.
- An unknown netAction went down neither path and never finished.
