[libvirt] [PATCH v3 20/36] network: convert networkReleaseActualDevice to virNetworkPortDef

Tue Mar 19 12:46:44 UTC 2019
Convert the virDomainNetDef object into a virNetworkPortDef object
at the start of networkReleaseActualDevice. This largely decouples
the method impl from the domain object type.
