[ Upstream commit 9bf2e9165f90dc9f416af53c902be7e33930f728 ]
When a 'DEL_CLIENT' message is received from the remote, the corresponding server port gets deleted. 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.
