Michael S. Tsirkin b4b9862b53 virtio: Fix no interrupt when not creating msi controller
For ARM virt machine, if we use virt-2.7 which will not create ITS node,
the virtio-net can not recieve interrupts so it can't get ip address
through dhcp.
This fixes commit 83d768b(virtio: set ISR on dataplane notifications).
