scsi: sd: enable compat ioctls for sed-opal 

The sed_ioctl() function is written to be compatible between
32-bit and 64-bit processes, however compat mode is only
wired up for nvme, not for sd.

Add the missing call to sed_ioctl() in sd_compat_ioctl().

Fixes: d80210f25f ("sd: add support for TCG OPAL self encrypting disks")
