nvme-pci: ensure we're polling a polled queue (CVE-2026-31523)

Summary

nvme-pci: ensure we're polling a polled queue

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

nvme-pci: ensure we're polling a polled queue

A user can change the polled queue count at run time. There's a brief
window during a reset where a hipri task may try to poll that queue
before the block layer has updated the queue maps, which would race with
the now interrupt driven queue and may cause double completions.
