driver core: class: fix slab-use-after-free Read in class_register()
Syzbot found that we had forgotten to unregister the lock_class_key when
using it in commit dcfbb67e48a2 ("driver core: class: use lock_class_key
already present in struct subsys_private") so fix that up and correctly
release it when done.
