[PATCH] net/mlx5_core/pagealloc: Remove deprecated create_singlethread_workqueue

[Bhaktipriya Shridhar]

A dedicated workqueue has been used since the work items are being used
on a memory reclaim path. WQ_MEM_RECLAIM has been set to guarantee forward
progress under memory pressure.

The workqueue has a single work item. Hence, alloc_workqueue() is used
instead of alloc_ordered_workqueue() since ordering is unnecessary when
there's only one work item.

Explicit concurrency limit is unnecessary here since there are only a
fixed number of work items.
