The workqueue "callback_wq" queues a single work item &cb->cb_work per
nfsd4_callback instance and thus, 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 not been set since this is an in-kernel nfs
server and isn't involved in memory reclaim operations on the local
host.
Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.
