Commit 5fff41e1f89d ("IB/core: Fix race condition in resolving IP to MAC")
changed the workqueue "addr_wq" to a single-threaded wq.
Commit e19c0d237873 ("RDMA/rdma_cm: Remove process_req and timer sorting")
eliminated global work and started using per-req work.
Now we no longer have the race, change "addr_wq" back to multi-threaded
workqueue to speed up multiple addr resolutions.
Fixes: e19c0d237873 ("RDMA/rdma_cm: Remove process_req and timer sorting")
