block/null_blk: add queue_rqs() support
Add batched mq_ops.queue_rqs() support in null_blk for testing. The
implementation is much easy since null_blk doesn't have commit_rqs().
We simply handle each request one by one, if errors are encountered,
leave them in the passed in list and return back.
There is about 3.6% improvement in IOPS of fio/t/io_uring on null_blk
with hw_queue_depth=256 on my test VM, from 1.09M to 1.13M.
