fix the layer touch recover, using the Scene:

add layer XX into the scene. and setTouchEnabled false, then, remove XX from the scene,but not release. at last , add XX into scene again, it will setTouchEnable true. So, this is a bug, the layer add into scene again, the touch state need to same with  it onExit
