rpcClient should attempt a reconnect if the call fails with 'rpc.ErrShutdown' this is needed since at times when the servers are taken down and brought back up. The hijacked connection from net.Dial is usually closed. So upon first attempt rpcClient might falsely indicate that disk to be down, to avoid this state make another dial attempt to really fail. Fixes #3206 Fixes #3205
