HID: logitech: Disable hi-res scrolling on USB
On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.
If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.
Disable hi-res scrolling on those devices until we implement scroll
events through HID++.
