Commit 47cab734995fa9521b1df05d37e9978eedd8d3a2 changed the way how qemud_client_message objects were reused. Before this commit remoteDispatchClientRequest() reused the received message for normal responses and to report non-fatal errors. If a fatal error occurred qemudWorker() frees the message. After this commit non-fatal errors are reported by remoteSerializeReplyError() using a new qemud_client_message object and the original message leaks. To fix this leak the original message has to be freed if remoteSerializeReplyError() succeeds. If remoteSerializeReplyError() fails the original message is freed in qemudWorker(). * daemon/dispatch.c: free qemud_client_message objects that will not be reused and would leak otherwise, also free the allocated qemud_client_message object in remoteSerializeError() if an error occurs
