HID: adjust report descriptor fixup for MS 1028 receiver 

Report descriptor fixup for MS 1028 receiver changes also values for
Keyboard and Consumer, which incorrectly trims the range, causing correct
events being thrown away before passing to userspace.

We need to keep the GenDesk usage fixup though, as it reports totally bogus
values about axis.
