    ukbd(4): Avoid races in LED setting on attach.

    - Don't reuse sc_delay for LED task -- a keyboard interrupt shortly
      after attach might reset sc_delay so that the LEDs never get turned
      back off.

    - Don't turn the LEDs back off after attach if something else has
      already changed them by the time the callout fires.

    (And make sure to callout_halt before done this time!)
