Devm_ functions allocate memory that is released when a driver detaches.

With conccurency managed workqueues, use of dedicated workqueues can be replaced by system_wq. Drop cvm_oct_poll_queue by using system_wq. There are multiple work items per cvm_oct_poll_queue (viz. cvm_oct_rx_refill_work, port_periodic_work) and different cvm_oct_poll_queues need not be be ordered. Hence, concurrency can be increased by switching to system_wq. All work items are sync canceled in cvm_oct_remove() so it is guaranteed that no work is in flight by the time exit path runs.
