KVM: Move irq routing to generic code
The IRQ routing set ioctl lives in the hacky device assignment code inside of KVM today. This is definitely the wrong place for it. Move it to the much more natural kvm_main.c. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com>
