On powernv, when removing a device through hotplug, the following warning is logged: Invalid refcount <.> on <...> It may be incorrect, the refcount may be set to a higher value than 1 and be valid. of_detach_node() can drop more than one reference. As it doesn't seem trivial to assert the correct value, let's remove the warning.
