[Xen-devel] [PATH]: Add missing spin_unlock_irq() to x86

[Juan Quintela <quintela@xxxxxxxxxx>]

Add missing spin_unlock_irq() at xen/arch/x86/irq.c

Changeset 9889:42a8e3101c6c reorganized the code on this file, and
missed this spin_unlock_irq().  Without this patch, my machine hang
completely during boot.  With this, it works.
