[Settings] Stop listening data connected intent for presenting reset APN dialog

Suspening the monitering of intent(TelephonyIntents.ACTION_ANY_DATA_CONNECTION_STATE_CHANGED)
during the stage of resetting default APN, since its more like a noice
once the reset progress stared (since user pressed the menu button).
