Subject: [PATCH AUTOSEL 6.0 58/67] nvmet: don't look at the request_queue in nvmet_bdev_zone_mgmt_emulate_all

From: Christoph Hellwig <hch@....de>

[ Upstream commit 8df20252c06046ef4c68107bcaaca56c21028d8c ]

nvmet is a consumer of the block layer and should not directly look at
the request_queue.  Just use the NUMA node ID from the gendisk instead of
the request_queue.
