Subject: [xen] irq: remove superfluous printk

O-Subject: [RHEL 5.4 PATCH] remove superfluous printk bz456095

When doing live migrate of a system, we take down all the CPUs
through CPU hotplug.  This will trigger the printk, which is
harmless except for the fact that people keep calling support
about it.

Fixes bug 456095
