Fix php8 error in function.php

[jh23453]

I got the message:
PHP Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?
in /usr/share/ganglia-webfrontend/functions.php on line 732

This messages is likely new with php7.3. Will be an error with PHP8.
For details see https://wiki.php.net/rfc/continue_on_switch_deprecation

This in one small step to get ready for php8. See #361

I now think that the following change would be better (pseudo-patch):

  case "standard":
    // Does view have any items/graphs defined
-    if ( count($view['items']) == 0 ) {
+    if ( count($view['items']) != 0 ) {
-      continue;
-      // print "No graphs defined for this view. Please add some";
-    } else {
      // Loop through graph items
      foreach ($view['items'] as $item_id => $item) {
