mm: Remove kmem_valid_obj()
Function kmem_dump_obj() will splat if passed a pointer to a non-slab object. So nothing calls it directly, instead calling kmem_valid_obj() first to determine whether the passed pointer to a valid slab object. This means that merging kmem_valid_obj() into kmem_dump_obj() will make the code more concise. Therefore, convert kmem_dump_obj() to work the same way as vmalloc_dump_obj(), removing the need for the kmem_dump_obj() caller to check kmem_valid_obj(). After this, there are no remaining calls to kmem_valid_obj() anymore, and it can be safely removed.
