[PATCH] efi: Set shim_lock_enabled even if validation is disabled

[Julian Andres Klode]

If validation has been disabled via MokSbState, secure boot on the
firmware is still enabled, and the kernel fails to boot.

This is a bit hacky, because shim_lock is not *fully* enabled, but
it triggers the right code paths.

Ultimately, all this will be resolved by shim gaining it's own image
loading and starting protocol, so this is more a temporary workaround.

Fixes: 6425c12cd (efi: Fallback to legacy mode if shim is loaded on x86 archs)
