#1472728 — [PATCH 5/9] fs/ocfs2/dlmfs: Remove deprecated create_singlethread_workqueue

The workqueue "user_dlm_worker" queues a single work item
&lockres->l_work per user_lock_res instance and hence it doesn't require
execution ordering. Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.

The WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure.

Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.
