Add below code in your master page, this will redirect to root site if user try to access subsite.

$(document).ready(function() {
       var siteUrl = _spPageContextInfo.siteServerRelativeUrl;
       var webUrl = _spPageContextInfo.webServerRelativeUrl;
       var isRootWeb = siteUrl == webUrl;
       if(isRootWeb == false){
        window.location.replace(_spPageContextInfo.siteAbsoluteUrl);
       }
 });
