Javier Martinez Canillas c3037730d4 acpi: Don't register the acpi command when locked down
The command is not allowed when lockdown is enforced. Otherwise an
attacker can instruct the GRUB to load an SSDT table to overwrite
the kernel lockdown configuration and later load and execute
unsigned code.

Fixes: CVE-2020-14372
