Ard Biesheuvel c2999c281e efifb: Omit memory map check on legacy boot ... Since the following commit: 38ac0287b7 ("fbdev/efifb: Honour UEFI memory map attributes when mapping the FB") efifb_probe() checks its memory range via efi_mem_desc_lookup(), and this leads to a spurious error message: EFI_MEMMAP is not enabled at every boot on KVM. This is quite annoying since the error message appears even if you set "quiet" boot option. Since this happens on legacy boot, which strangely enough exposes a EFI framebuffer via screen_info, let's double check that we are doing an EFI boot before attempting to access the EFI memory map.
