efifb_probe() will issue an error message in case the kernel is booted
as Xen dom0 from UEFI as EFI_MEMMAP won't be set in this case. Avoid
that message by calling efi_mem_desc_lookup() only if EFI_PARAVIRT
isn't set.

In case I see no reaction from the maintainer for another week I'll take
this patch through the Xen tree.
