USB HID: Changed/removed wrong comment.

 * The HID driver publishes devices for all handlers that claim
   to know how to work with a device. I see how that is good for
   a combo device like keyboard with built-in touch pad or a single
   USB receiver for a keyboard and mouse. But I wonder about devices
   that publish multiple alternative HID configurations. I think
   my Wacom Tablet has a configuration for a regular mouse and the
   configuration for the actual tablet. And the driver should publish
   a device for one, but not the other. I also don't see in the code
   how a specific configuration is made the active one before the
   protocol is used.
USB HID: Restore previous handler sorting.

 * Since additional handlers put themself in the front the
   handler list, asking the tablet handler last actually puts
   its handler in the first position, as before my changes.
