KVM: VMX: don't configure EPT identity map for unrestricted guest
An unrestricted guest can run with hardware CR0.PG==0, i.e. IA32 paging disabled, in which case there is no need to load the guest's CR3 with identity mapped IA32 page tables since hardware will effectively ignore CR3. If unrestricted guest is enabled, don't configure the identity mapped IA32 page table and always load the guest's desired CR3.
