[ Upstream commit bc5519c18a32ce855bb51b9f5eceb77a9489d080 ]

Commit 2e27f576abc6 ("scsi: scsi_ioctl: Call scsi_cmd_ioctl() from
scsi_ioctl()") seems to have a typo as it is checking ret instead of cmd in
the if statement checking for CDROMCLOSETRAY and CDROMEJECT.  This changes
the behaviour of these ioctls as the cdrom_ioctl handling of these is more
restrictive than the scsi_ioctl version.
