SMM emulation under both KVM and QEMU (TCG) crashes the guest when the "jz" branch, added in commitd4d87596c1("UefiCpuPkg/PiSmmCpuDxeSmm: Enable NXE if it's supported", 2018-01-18), is taken. Rework the propagation of CPUID.80000001H:EDX.NX [bit 20] to IA32_EFER.NXE [bit 11] so that no code is executed conditionally.
