A DEL_SERVER message is then announced for this server. As part of handling the subsequent DEL_SERVER message, the name- server attempts to delete the server port which results in a '-ENOENT' error. The return value from server_del() is then propagated back to qrtr_ns_worker, causing excessive error prints. To address this, return 0 from control_cmd_del_server() without checking the return value of server_del(), since the above scenario is not an error case and hence server_del() doesn't have any other error return value.
