[PATCH] HID: Invert HWHEEL mappings for some Logitech mice

[Dan Nicholson <dbn.lists@gmail.com>]

Some Logitech mice have a tilt wheel which register as HWHEEL buttons.
The events are positive for a click to the right and negative for a
click to the left. Applications expect the opposite, though.

I suspect this affects a lot more Logitech mice, but these are the only
two I have. I tested this using evtest and a GTK application. A similar
Microsoft Intellimouse I have works correctly.
