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.
