There are two reasons we need to use x86_hyper instead of query_hypervisor_presence(): - Not only hyperv but also other hypervisors such as kvm would set X86_FEATURE_HYTPERVISOR, so query_hypervisor_presence() will return true even in kvm. This may cause extra delay of 5 seconds before failing the probing in kvm guest. - The hypervisor has been detected in init_hypervisor(), so no need to do the work again.
