The check for in-kernel irqchip must be protected by kvm_enabled, and we
have a different wrapper for it.

Why not move kvm_enabled() into kvm_irqchip_in_kernel()? It will return
false if !kvm_enabled().
Yes, possible. But I'm not sure if it's worth to refactor at this level.

In any case, fix bugs first, refactor later.

I think the whole irqchip interface has to go through some broader
refactoring when pushing it upstream. The result should either be a
specific, in-kernel-irqchip apic device or generic wrapper services that
cover all cases, is easily compiled away in the absence of KVM and avoid
#ifdefs like below.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
