[PATCH linux v2 6/9] xen/events: use xen_vcpu_id mapping in events_base

[Vitaly Kuznetsov <vkuznets@redhat.com>]

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.
