block: skip QUEUE_FLAG_STATS and rq-qos for passthrough io
Write-back throttling (WBT) enables QUEUE_FLAG_STATS on the request
queue. But WBT does not make sense for passthrough io, so skip
QUEUE_FLAG_STATS processing.
Also skip rq_qos_issue/done for passthrough io.
Overall, the change gives ~11% hike in peak performance.
