IB/mlx4/mad: Remove deprecated create_singlethread_workqueue
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "wq" queues work item &ctx->work and the workqueue "ud_wq"
queues work item &dm[i]->work.
Both the workqueues have been identity converted.
WQ_MEM_RECLAIM has been set to ensure forward progress under
memory pressure.
