The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single
work item &ioc->fault_reset_work and &fw_event->work, respectively and
hence don't require ordering. Hence, they have been converted to use
alloc_workqueue().
The WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure since the workqueue belongs to a storage driver which is
being used on a memory reclaim path.
Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.
