Urgh.  HVMIRQ_callback_vector is the one that is utterly broken, and
doesn't conform to the Local APIC spec, and must not end up in IRR.

We still need to figure out how to prevent a domain using
HVMIRQ_callback_vector when hardware APIC acceleration is in use, but
that's definitely getting off topic for this patch.
