scsi: sd: Fix error handling in sd_probe() after large pool creation failure

Browse source

After device_add(&sdkp->disk_dev) succeeds, sd_large_pool_create()
failure must unregister disk_dev and let scsi_disk_release() free
sdkp. Going through out_free_index kfree()s an already registered device
and leaks the sysfs entry.
