- It is an error if system_state is not set properly.

-  Do to my earlier cleanups there are only 4 functions
   that call device_shutdown they are:
   kernel_restart(), kernel_kexec(), kernel_halt(), kernel_power_off()

   And those four all set system_state correctly.

If you can find another path that calls this incorrectly I would be happy
to fix it.  But my grep through the kernel doesn't reveal any other
