The right config should be

     server {
         listen  80 default_server;
         server_name  _;  # just nonexistant domain name
         rewrite    ^   http://www.domain.tld$request_uri? permanent;
     }

     server {
         listen  80;
         server_name  .domain.tld;
                     # www.domain.tld is matched by .domain.tld;
         ...
     }
