watchdog messages for solr delete queries ignore "Log successful Apache Solr Search actions" setting

#2008832 Allow to optionally turn of "successful" actions in watchdog provides a setting to reduce the number of watchdog messages that the module logs.

The setting is not applied to watchdog messages from apache solr delete queries in apachesolr.index.inc.

e.g.

  // Log the query used for deletion.
  watchdog('Apache Solr', 'Deleted documents from index with query @query', array('@query' => $query), WATCHDOG_INFO);

should be, following the example

  // Log the query used for deletion.
  $log_success = variable_get('apachesolr_watchdog_successes', TRUE);
  if ($log_success) {  
    watchdog('Apache Solr', 'Deleted documents from index with query @query', array('@query' => $query), WATCHDOG_INFO);
  }

Besides three instances in apachesolr.index.inc, I don't see any other watchdog messages for successful queries that don't check the setting.
