  SVN rev 220649 on 2011-04-15 03:09:27Z by np
  
  Fix a couple of bad races that can occur when a cxgbe interface is taken
  down.  The ingress queue lock was unused and has been removed as part of
  these changes.
  
  - An in-flight egress update from the SGE must be handled before the
    queue that requested it is destroyed.  Wait for the update to arrive.
  
  - Interrupt handlers must stop processing rx events for a queue before
    the queue is destroyed.  Events that have not yet been processed
    should be ignored once the queue disappears.
