[libvirt] [PATCH v4 01/29] network: ensure floor sum is reset to zero when starting networks

In extreme cases libvirt can get mixed up about what VMs are running and attached to a network leading to the cached floor sum value being outdated. When this happens the only option is to destroy the network and then restart libvirtd. If we set floor sum back to zero when starting the network, we avoid the need for a libvirtd restart at least.
