Subject: [PATCH 5.18 083/339] scsi: sd: Dont call blk_cleanup_disk() in sd_probe()

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

[ Upstream commit 7274ce0558adb4b9b1f5c5b613fb4fe331c18911 ]

In SCSI the midlayer has ownership of the request_queue, so on probe
failure we must only put the gendisk, but leave the request_queue alone.

Fixes: 03252259e18e ("scsi: sd: Clean up gendisk if device_add_disk() failed")
