FIX: towards Drupal 6 port of Node Import - "Call-time pass-by-reference has been deprecated" errors

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in /home/virtual/site32/fst/var/www/html/sites/all/modules/node_import/node_import.admin.inc on line 560

These errors can be easily fixed by removing the unneeded reference thingy on several of the function calls.

On lines 560, 565, 572 of node_import.admin.inc, you should replace this:

node_import_add_form_submit_reload($form, &$form_state);

with this:

node_import_add_form_submit_reload($form, $form_state);

Sorry for lack of patch.
