 If during attach() a device for some reason fails to initialize, there are
 cases where gDeviceCount will not be decremented (specially when using
 iflib) as the place where this happens currently is never called in that
 case. So even if the device is not successfully initialized, the driver is
 not unloaded and the /dev entry still hangs around.

 We probably want to move the handling to a higher abstraction or simply
 remove it (it is not obvious to me if it is used outside the compatibility
 layer).
