HID: wacom: leds: Don't try to control the EKR's read-only LEDs

commit 74aebed6dc13425233f2224668353cff7a112776 upstream.

Commit a50aac7193f1 introduces 'led.groups' and adds EKR support
for these groups. However, unlike the other devices with LEDs,
the EKR's LEDs are read-only and we shouldn't attempt to control
them in wacom_led_control().
