[Qemu-devel] [PATCH v2] kvm: Fix build for non-CAP_IRQ_ROUTING targets

[Jan Kiszka]

A type definition and a KVMState field initialization escaped the
required wrapping with KVM_CAP_IRQ_ROUTING. Also, we need to provide a
dummy kvm_irqchip_release_virq as virtio-pci references (but does not
use) it.

Changes in v2:
 - include the missing kvm_irqchip_release_virq that Ben Collins found
