[ Upstream commit 6a4760463dbc6b603690938c468839985189ce0a ]
kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()：
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object.
Fix memory leak by calling kobject_put().
Fixes: 8c0984e5a753 ("power: move power supply drivers to power/supply")
