Subject: [PATCH] scsi: sr: fix typo in CDROM(CLOSETRAY|EJECT) handling

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.

Fixes: 2e27f576abc6 ("scsi: scsi_ioctl: Call scsi_cmd_ioctl() from scsi_ioctl()")
