KVM: SVM: Fix EFER.LME being stripped 

Must set VCPU register to be the guest notion of EFER even if that
setting is not valid on hardware.  This was masked by the set in
set_efer until 7657fd5ace88e8092f5f3a84117e093d7b893f26 broke that.
Fix is simply to set the VCPU register before stripping bits.
