kobject: don't use WARN for registration failures
commit 3e14c6abbfb5c94506edda9d8e2c145d79375798 upstream.
This WARNING proved to be noisy. The function still returns an error
and callers should handle it. That's how most of kernel code works.
Downgrade the WARNING to pr_err() and leave WARNINGs for kernel bugs.
