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.
