selftests: ublk: add generic_01 for verifying sequential IO order
block layer, ublk and io_uring might re-order IO in the past
- plug
- queue ublk io command via task work
Add one test for verifying if sequential WRITE IO is dispatched in order.
- null target is taken, so we can just observe io order from
`tracepoint:block:block_rq_complete` which represents the dispatch order
- WRITE IO is taken because READ may come from system-wide utility
