scsi: core: Fix a comment in function scsi_host_dev_release()
[ Upstream commit 2dde5c8d912efea43be94d6a83ac9cb74879fa12 ]
Commit 3be8828fc507 ("scsi: core: Avoid that ATA error handling can
trigger a kernel hang or oops") moved rcu to scsi_cmnd instead of
shost. Modify "shost->rcu" to "scmd->rcu" in a comment.
