[PATCH] efi: x86: Fix config name for setting the NX-compatibility flag in the PE header

[Lukas Bulwahn]

Commit 21b68da7bf4a ("efi: x86: Set the NX-compatibility flag in the PE
header") intends to set the compatibility flag, i.e.,
IMAGE_DLL_CHARACTERISTICS_NX_COMPAT, but this ifdef is actually dead as the
CONFIG_DXE_MEM_ATTRIBUTES does not exist.

The config is actually called EFI_DXE_MEM_ATTRIBUTES. Adjust the ifdef to
use the intended config name.

The issue was identified with ./scripts/checkkconfigsymbols.py.
