kobject: don't use WARN for registration failures
[ Upstream commit 3e14c6abbfb5c94506edda9d8e2c145d79375798 ]
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.
