[PATCH] APM Screen Blanking fix

- Fix screen blanking on BIOSes that return APM_NOT_ENGAGED when APM enabled
  screen blanking is not turned on.

  The original code only tried to set the state on device 0x100, and then
  0x1FF, and I added 0x101 to the mix too.

- Clean up logic in apm_console_blank().

- Prevent the error message from printing out twice.
