xen/events: use xen_vcpu_id mapping in events_base
EVTCHNOP_bind_ipi and EVTCHNOP_bind_virq pass vCPU id as a parameter and Xen's idea of vCPU id should be used. Use the newly introduced xen_vcpu_id mapping to convert it from Linux's id. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: David Vrabel <david.vrabel@citrix.com>
