Unblank display when shutting down/rebooting from act dead or user mode

Previously display was blanked when shutting down from act dead. As there
is now shutdown animation also for act dead, that is no longer desirable.

Unblanking the display makes the animation visible even if the shutdown
or reboot happened from display off state without user interaction.
