fs/afs/flock: Remove deprecated create_singlethread_workqueue
The workqueue "afs_lock_manager" queues work item &vnode->lock_work, per vnode. Since there can be multiple vnodes and since their work items can be executed concurrently, 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 because the workqueue is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.
