Paolo Bonzini 9c2f09add6 KVM: nVMX: add missing consistency checks for CR0 and CR4 
commit 112e66017b upstream.

The effective values of the guest CR0 and CR4 registers may differ from
those included in the VMCS12.  In particular, disabling EPT forces
CR4.PAE=1 and disabling unrestricted guest mode forces CR0.PG=CR0.PE=1.

Therefore, checks on these bits cannot be delegated to the processor
and must be performed by KVM.
