blk_execute_rq_nowait() function mainly was used by low-level drivers such as NVMe to submit one-off passthrough requests. However, recently introduced uring-cmd based io-passthrough also uses the same function to submit io requests. As the plugging support is coming to io-passthrough[1], use the blk_mq_plug() helper to ensure plugging is not used in all scenarios.
