The\nproblem is that when we do \"device_del\" we normally looking for two\nthings: one response (which is mostly empty), and a REMOVE event. The\ntricky point is the event can either be there before/after the empty\nresponse. So I added qmp_device_del() to make sure the order does not\nmatter, then use it where proper.\n\nSince I'm at it, I also added the sister helper qmp_device_add(), it\nhelps to remove LOCs.\n\nI still don't 100% sure why my private tree can trigger this error,\nwhile the master cannot. Anyway, I think this is something we should\nhave, no matter what.\n\nPlease review.
