Laszlo Ersek 8d4d55b15b UefiCpuPkg/PiSmmCpuDxeSmm: eliminate conditional jump in IA32 SmmStartup() 
SMM emulation under both KVM and QEMU (TCG) crashes the guest when the
"jz" branch, added in commit d4d87596c1 ("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.
