x86/efi: Fix 32-bit fallout
We do not enable the new efi memmap on 32-bit and thus we need to run runtime_code_page_mkexec() unconditionally there. Fix that. Reported-and-tested-by: Lejun Zhu <lejun.zhu@intel.com> Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
