BugLink: https://bugs.launchpad.net/bugs/2097301 [ Upstream commit 224de6f886f8184fd448700a6d78f216694de948 ] Sometime, it would be useful to disable the configure change notification from the driver. So this patch allows this by introducing a variable config_change_driver_disabled and only allow the configure change notification callback to be triggered when it is allowed by both the virtio core and the driver. It is set to false by default to hold the current semantic so we don't need to change any drivers. The first user for this would be virtio-net.
