[ Upstream commit 0296bea01cfa6526be6bd2d16dc83b4e7f1af91f ]
"if device_add() succeeds, you should call device_del() when you want to get rid of it."
In sd_probe(), device_add_disk() fails when device_add() has already succeeded, so change put_device() to device_unregister() to ensure device resources are released.
