Revert "kobject: Make sure the parent does not get released before its children"
This reverts commit 4ef12f7198023c09ad6d25b652bd8748c965c7fa. Guenter reports: All my arm64be (arm64 big endian) boot tests crash with this patch applied. Reverting it fixes the problem. Crash log and bisect results (from pending-fixes branch) below. And also: arm64 images don't crash but report lots of "poison overwritten" backtraces like the one below. On arm, I see "refcount_t: underflow", also attached. I didn't bisect those, but given the context I would suspect the same culprit.
