[Libvir] PATCH: Force close of virConnectPtr if client quits abnormally

[Daniel P. Berrange]

If a remote client quits abnormally (or if the server forcably drops a
client for misbehaviing), it is possible that the virConnectPtr object
is not closed. This leads to a build up of active connections in the
server. The attached patch simply calls virConnectClose when killing off
a client connection if there is a non-NULL client->conn object.

Dan.
