efi: Allow EFI_MEMORY_XP and EFI_MEMORY_RO both to be cleared

UEFI spec 2.9, p.108, table 4-1 lists the scenario that both attributes
are cleared with the description "No memory access protection is
possible for Entry". So we can have valid entries where both attributes
are cleared, so remove the check.
