[PATCH] kobject_add() must have a valid name in order to succeed.

[PATCH] kobject_add() must have a valid name in order to succeed.

So we might as well check to verify this, and let the user know that
something is wrong if they didn't do it correctly, instead of oopsing
later on in kobject_get_name() or somewhere else.
