[libvirt] [PATCH 06/21] Misc cleanup to network socket init



* daemon/libvirtd.c: Change qemudNetworkInit() so that it doesn't try
to free its argument, leaving the caller todo cleanup as is normal
practice. Add missing policykit cleanup to qemudCleanup, and remove
server watch if set. Remove duplicated call to listen() on TCP sockets
