scsi: core: Fix a comment in function scsi_host_dev_release()

[ Upstream commit 729170e7be486f6f6db0f72ad710ba7652edbca8 ]

Commit f0fc58cf49bb ("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.
