Anyone using these functions has to be prepared that irqchip
support may not be present. It shouldn't be up to the core
code to determine whether this is a fatal error. Currently
code written as:
virq = kvm_irqchip_add_msi_route(...)
if (virq < 0) {
<slow path>
} else {
<fast path>
}
works on x86 with and without kvm irqchip enabled, works
without kvm support compiled in, but aborts() on !x86 with
kvm support.
