commit 91d20ab9d9ca035527af503d00e1e30d6c375f2a upstream.
Since wiphy work items can run pretty much arbitrary code in the stack/driver, it can take longer to run all of this, so we shouldn't be using system_wq via schedule_work(). Also, we lock the wiphy (which is the reason this exists), so use system_unbound_wq.
