  Fix a memory leak associated with queues.
  
  For every attempt that app_queue made to place an outbound call to a queue member,
  we would allocate a queue_end_bridge structure. When the bridge for the call had
  completed, we would free the structure. Unfortunately not all call attempts actually
  end up bridged to a member, so we need to be more selective of when to allocate
  the structure. With this change, the allocation occurs in an area where we can
  guarantee that the call will be bridged.
