[libvirt] [PATCH 03/11] Replace virNetworkFree with virObjectUnref
John Ferlan

Mon Dec 1 15:56:17 UTC 2014
Since virNetworkFree will call virObjectUnref anyway, let's just use that
directly so as to avoid the possibility that we inadvertently clear out
a pending error message when using the public API.
