    rx: Correctly test for end of call queue
    
    The intention of this condition is to check if the current call
    being considered is the last one on the queue, but the test is
    incorrect.  A null next pointer indicates a removed item, not
    the end of the queue.
    
    Use the queue_IsLast macro instead to correctly determine that
    this is the last item in the queue and that a call has to be
    selected, either the current one or a previously seen good choice.
    
    This can cause calls to get permanently stuck in the call queue
    and never get assigned to a thread, even when all threads are
    idle.
