KVM: x86: avoid loading a vCPU after .vm_destroy was called
This can cause various unexpected issues, since VM is partially
destroyed at that point.
For example when AVIC is enabled, this causes avic_vcpu_load to
access physical id page entry which is already freed by .vm_destroy.
Fixes: 8221c1370056 ("svm: Manage vcpu load/unload when enable AVIC")
