[PATCH AUTOSEL 5.19 56/63] nvmet: don't look at the request_queue in nvmet_bdev_set_limits

[Sasha Levin]

From: Christoph Hellwig <hch at lst.de>

[ Upstream commit 84fe64f898913ef69f70a8d91aea613b5722b63b ]

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.
