HID: ignore all non-LED usages in output fields in hid-input
We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and
output reports with different parameters will mess things up. In
hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.
Fixes auto-calibration for Saitek Cyborg Evo Force joystick.
