Oh! Any chance the bug only repros with preemption enabled? That would explain
why I don't see problems, I'm pretty sure I've only run AVIC with a PREEMPT=n.
svm_vcpu_{un}blocking() are called with preemption enabled, and avic_set_running()
passes in vcpu->cpu. If the vCPU is preempted and scheduled in on a different CPU,
-avic_vcpu_load() will overwrite the vCPU's entry with the wrong CPU info.
