Decrementing struct spdk_jsonrpc_server_conn::outstanding_requests should be atomic since this variable are accesed from multiple threads. Istead of that just route the request back to the server thread with nothing to send. As we are here change spdk_jsonrpc_server_send_response() to take only struct spdk_jsonrpc_request parameter.
