[libvirt] [PATCH 3/4] rpc: Fix handling of non-blocking calls that could not be sent

[Jiri Denemark]

When virNetClientIOEventLoop is called for a non-blocking call and not
even a single byte can be sent from this call without blocking, we
properly reported that to the caller which properly frees the call. But
we never removed the call from a call queue.
