Subject: [PATCH 13/17] xen: initialize irq 0 too

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@...rix.com>

IRQ 0 is valid, so make sure it gets initialized properly too.
(Though in practice it doesn't matter, because its the timer
interrupt we don't use under Xen.)

[ Impact: theoretical bugfix, cleanup ]
