Ard Biesheuvel 52e51f1640 efi/libstub: Treat missing SecureBoot variable as Secure Boot disabled ... The newly refactored code that infers the firmware's Secure Boot state prints the following error when the EFI variable 'SecureBoot' does not exist: EFI stub: ERROR: Could not determine UEFI Secure Boot status. However, this variable is only guaranteed to be defined on a system that is Secure Boot capable to begin with, and so it is not an error if it is missing. So report Secure Boot as being disabled in this case, without printing any error messages.
