HID: fix hidbus/appletouch device binding regression 



The appletouch mouse devices are grabbed by the hid bus and not
released even if apple driver says ENODEV (as expected) -- these
are composite USB devices, for which we only ignore the mouse
interface. This is currently not handled by hidbus code properly.

Move the ignoring one level upper to forbid the hid layer to grab the
device.
