        return;

The check will go wrong here, because after

    for (queue_id = MAX_BATTLEGROUND_QUEUES-1; queue_id >= 0; queue_id--)
   {
       itr = m_QueuedPlayers[queue_id].find(guid);
       if(itr != m_QueuedPlayers[queue_id].end())
           break;
   }

if no player is found, it will have -1 in queue_id, so m_QueuedPlayers[queue_id] has no sense.
