[PATCH 2/2] HID: input: fix assignment of .value

[Benjamin Tissoires]

The value field is actually an array of .maxfield. We should assign the
correct number to the correct usage.

Not that we never encounter a device that requires this ATM, but better
have the proper code path.

Fixes: 2dc702c991e377 ("HID: input: use the Resolution Multiplier for
       high-resolution scrolling")
