Ján Tomko e68432e45f Properly unref a connection with a close callback
The connection pointer in the closeCallback data was never
initialized, making the unref in remoteClientCloseFunc a no-op.

This fixes the following leak in virsh when the daemon closes
the connection unexpectedly:

1,179 (288 direct, 891 indirect) bytes in 1 blocks are
   definitely lost in loss record 745 of 792

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
