Instead of adding locking to also protect irq_vector[] in xenlinux, this patch adds verification that the vector passed up from Xen for a certain IRQ is matching a potential previously obtained value. Besides that, two minor cleanup hunks.

I think the extra checking here adds pointless complexity. If the check fails then you are totally screwed -- you're just going to have to trust Xen here.
