nvmet: don't look at the request_queue in nvmet_bdev_set_limits
nvmet is a consumer of the block layer and should not directly look at the request_queue. Use the bdev_ helpers to retrieve the device limits instead. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Keith Busch <kbusch@kernel.org>
