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.

Why not test for EFI_MEMMAP instead of EFI_BOOT?

Honestly I'm not sure EFI_BOOT is always set in that case. If you tell
me it is fine to just replace the test to check for EFI_MEMMAP I'm fine
to modify my patch.
