Subject: xen/events: Set irq_info->evtchn before binding the channel to CPU in __startup_pirq()

From: Boris Ostrovsky <boris.ostrovsky@oracle.com>

commit 16e6bd5970c88a2ac018b84a5f1dd5c2ff1fdf2c upstream.

.. because bind_evtchn_to_cpu(evtchn, cpu) will map evtchn to
'info' and pass 'info' down to xen_evtchn_port_bind_to_cpu().
