To better match bdev modules like nvme, complete requests for the bdev/null driver asynchronously. This will be done by allocating IO channels that register a poller and keep a TAILQ of bdev IO to be completed next time the poller runs. This is actually more efficient as well, since completing I/O in submit_request context defers the completion using an event. A benchmark of bdevperf with split running on top of null module shows this patch increases throughput 20%.
