Don't wait for unnecessary disconnect broadcast
testTetheringUpstream does not require WIFI to be default
network since the test disconnects WIFI and verifies that
tethering use cellular network to be its upstream. Test only
needs to ensure WIFI is disconnected so the broadcast is not
necessary. Change to alternative method that does not wait for
disconnect broadcast to prevent flaky caused by unvalidated
wifi network.
