HID: logitech: Disable hi-res scrolling on USB

commit 690eb7dec72ae52d1d710d14a451844b4d0f4f19 upstream.

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++.
