create_workqueue always creates the workqueue with WQ_MEM_RECLAIM
and silences a flush dependency warn for WQ_LEGACY. Instead, we
want to keep the warn in case the allocator tries to flush the
cm workqueue because its very likely that cm work execution will
yield memory allocations (for example cm connection requests).
