Revert "KVM: VMX: Read 32-bit GPR values for ENCLS instructions outside of 64-bit mode"
Now that kvm_<reg>_read() are mode aware, i.e. are functionally equivalent
to kvm_register_read(), revert aback to the less verbose versions.
No functional change intended.
This reverts commit 60919eccf6764c71cef31a1afeaa1a36b8e5ab85.
