efi: avoid error message when booting under Xen

[ Upstream commit 6163a985e50cb19d5bdf73f98e45b8af91a77658 ]

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_MEMMAP is set.
