kvm: Don't abort on kvm_irqchip_add_msi_route() 



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.
