wa_urb_enqueue_run locks and unlocks its list lock as it traverses the list of queued transfers. This was done to prevent deadlocking due to acquiring locks in reverse order in different places. The problem is that releasing the lock during the list traversal could allow the dequeue routine to corrupt the list while it is being iterated over. This patch moves all list entries to a temp list while holding the list lock, then traverses the temp list with no lock held.
