Weng Su 98d30c880d Fix ConnectivityManager.requestNetwork crash issue when try again
- When the user requests "try again", the Network-Request-Dialog will be
  recreated. If the Wi-Fi framework sends the callback result at this
  time, the Network-Request-Dialog may not be ready at the moment,
  causing the NPE to crash.

- Add NPE checks to avoid crash issues.
