Subject: [PATCH] edac: wq: Remove deprecated create_singlethread_workqueue

alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.

wq has been identity converted since it is used to detect things like
ECC memory errors.  It's not recommended to stall it from memory pressure.
Hence, WQ_MEM_RECLAIM has been set to ensure forward progress under
memory pressure.
