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

Browse source

[ Upstream commit 166e31d7db ]

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.
