rpc: push ref acquisition into RPC dispatch function
|
|
|
|
There's no reason why the virNetServerClientDispatchRead method needs to
|
|
acquire an extra reference on the "client" object. An extra reference is
|
|
only needed if the registered dispatch callback is going to keep hold of
|
|
the "client" for work in the background. Thus we can push reference
|
|
acquisition into virNetServerDispatchNewMessage.
