slub: Fix kmem_ptr_validate() for non-kernel pointers
As suggested by Linus, fix up kmem_ptr_validate() to handle non-kernel pointers more graciously. The patch changes kmem_ptr_validate() to use the newly introduced kern_ptr_validate() helper to check that a pointer is a valid kernel pointer before we attempt to convert it into a 'struct page'.
