[libvirt] [PATCH] Fix leak of objects when reconnecting to QEMU instances

From: "Daniel P. Berrange" <berrange redhat com>

The 'error' cleanup block in qemuProcessReconnect() had a
'return' statement in the middle of it. This caused a leak
of virConnectPtr & virQEMUDriverConfigPtr instances. This
was identified because netcf recently started checking its
refcount in libvirtd shutdown:

netcfStateCleanup:109 : internal error: Attempt to close netcf state driver with open connections
