Note only does this leak the corresponding\nmemory when the vCPU is destroyed but it can also lead to use-after-free\nif the redistributor device handling tries to walk into the vCPU.\n\nAdd the missing cleanup to kvm_arch_vcpu_create(), ensuring that the\nvGIC vCPU structures are destroyed on error.",
