It is dangerous to shutdown the apics in machine_crash_shutdown.
With my previous patch to initialize apics in init_IRQ we should be able to
boot a kernel without this. As long as we reinitialize the APICs we don't
care what state they were in during bootup.
This should make machine_crash_shutdown noticeably more reliable.
