efi_loader: fix BootOrder variable measurement handling
UEFI specification does not require that BootOrder is defined.
In current implementation, boot variable measurement fails and
returns EFI_NOT_FOUND if BootOrder is not defined.
This commit correcly handles this case, skip the boot variable
measurement if BootOrder is not defined.
