 *   nt_kb_light_on
 *
 *   This code gets called whenever kbdhdw  tries to change the kbd leds.
 *   We cannot allow changes to the real leds because this would get us
 *   out of sync with user32 physical keyboard state. So what we do is
 *   to send fake keys to the kbd hdw to reset the state to what the
 *   the latest state is according to the console input
 *
 *   Caller should hold the kbd mutex
