Sebastien Boeuf b92fe648e9 vmm: cpu: Disable KVM_FEATURE_ASYNC_PF_INT in CPUID ...

By disabling this KVM feature, we prevent the guest from using APF
(Asynchronous Page Fault) mechanism. The kernel has recently switched to
using interrupts to notify about a page being ready, but for some
reasons, this is causing unexpected behavior with Cloud Hypervisor, as
it will make the vcpu thread spin at 100%.

While investigating the issue, it's better to disable the KVM feature to
prevent 100% CPU usage in some cases.
