KVM: MMU: pass arbitrary CR0/CR4/EFER to kvm_init_shadow_mmu

Browse source

This allows fetching the registers from the hsave area when setting
up the NPT shadow MMU, and is needed for KVM_SET_NESTED_STATE (which
runs long after the CR0, CR4 and EFER values in vcpu have been switched
to hold L2 guest state).
