Andy Shevchenko fb27c2eab5 kobject: Restore old behaviour of kobject_del(NULL)
commit 40b8b826a6998639dd1c26f0e127f18371e1058d upstream.

The commit 079ad2fb4bf9 ("kobject: Avoid premature parent object freeing in
kobject_cleanup()") inadvertently dropped a possibility to call kobject_del()
with NULL pointer. Restore the old behaviour.

Fixes: 079ad2fb4bf9 ("kobject: Avoid premature parent object freeing in kobject_cleanup()")
