    altq: Don't use poll cache
    
    The poll/dequeue model is no longer applicable to SMP system, e.g.
    
       CPU-A            CPU-B
         :                :
       poll               :
         :              poll
       dequeue (+)        :
    
    The dequeue at (+) will hit the poll cache set by CPU-B.
