[PATCH 05/14] sd: call sd_zbc_release_disk before releasing the scsi_device reference

From: Christoph Hellwig <hch@lst.de>
Date: 2022-02-27 17:22:11
Also in: linux-scsi
Subsystem: scsi subsystem, the rest · Maintainers: "James E.J. Bottomley", "Martin K. Petersen", Linus Torvalds

sd_zbc_release_disk accesses disk->device, so ensure that actually still has
a valid reference.
