HID: lenovo: Sync Fn-lock state on button press for Compact and TrackPoint II keyboards
When Fn-Esc is pressed on the keyboard, it emits the scancode which could be used to sync the fn_lock sysfs state. Previously fn_lock only allowed to set new Fn-lock state and did not keep the value in sync upon Fn-Esc press, which is now fixed.
