scsi: sd: Remove obsolete variable in sd_remove()

Commit 996e509bbc95 ("sd: use __register_blkdev to avoid a modprobe for an
unregistered dev_t") removed blk_register_region(devt, ...) in sd_remove()
and since then, devt is unused in sd_remove().

Hence, make W=1 warns:

  drivers/scsi/sd.c:3516:8:
      warning: variable 'devt' set but not used [-Wunused-but-set-variable]

Simply remove this obsolete variable.
