Fix an NPE that can result from a race condition.

NetworkInfo and WifiInfo are set via broadcast receiver so while in a
true stable state network info should not be null if wifi info is, this
can occur in rare instances due to a race condition. It is convention in
AccessPoint.java to always null check network info.
