messaging.install: Call-time pass-by-reference has been deprecated

lastest update (messaging_update_6003) calls db_change_field and tries to pass a variable by reference. Results in error:

Call-time pass-by-reference has been deprecated

Change line 201 of messaging.install from:

  db_change_field(&$ret, 'messaging_store', 'params', 'params', array('type' => 'text', 'not null' => TRUE, 'size' => 'big', 'serialize' => TRUE));

to:

  db_change_field($ret, 'messaging_store', 'params', 'params', array('type' => 'text', 'not null' => TRUE, 'size' => 'big', 'serialize' => TRUE));
