KVM: vmx: Inject #GP on invalid PAT CR

commit 4566654bb9be9e8864df417bb72ceee5136b6a6a upstream.

Guest which sets the PAT CR to invalid value should get a #GP.  Currently, if
vmx supports loading PAT CR during entry, then the value is not checked.  This
patch makes the required check in that case.
