s390: Remove deprecated create_singlethread_workqueue
The workqueue "appldata_wq" has been replaced with an ordered dedicated workqueue. WQ_MEM_RECLAIM has not been set since the workqueue is not being used on a memory reclaim path. The adapter->work_queue queues multiple work items viz &adapter->scan_work, &port->rport_work, &adapter->ns_up_work, &adapter->stat_work, adapter->work_queue, &adapter->events.work, &port->gid_pn_work, &port->test_link_work. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure.
