[libvirt] [PATCH v3 1/6] virNetSocket: allow to not close FD

[Pino Toscano]

Add an internal variable to mark the FD as "not owned" by the
virNetSocket, in case the internal implementation takes the actual
ownership of the descriptor; this avoids a warning when closing the
socket, as the FD would be invalid.
