[SCSI] SCSI sd: fix module init/exit error handling
- Properly handle and unwind errors in init_sd(). Fixes leaks on error,
if class_register() or scsi_register_driver() failed.
- Ensure that exit_sd() execution order is the perfect inverse of
initialization order.
FIXME: If some-but-not-all register_blkdev() calls fail, we wind up
calling unregister_blkdev() for block devices we did not register.
This was a pre-existing bug.
