KVM: SVM: Unregister KVM's GALog notifier on kvm-amd.ko exit
Unregister the GALog notifier (used to get notified of wake events for
blocking vCPUs) on kvm-amd.ko exit so that a KVM or IOMMU driver bug that
results in a spurious GALog event "only" results in a spurious IRQ, and
doesn't trigger a use-after-free due to executing unloaded module code.
Fixes: 5881f73757cc ("svm: Introduce AMD IOMMU avic_ga_log_notifier")
