So I'll do a minimal conversion that adds "memblock_free_ptr()" and
hope that people start using that. And then we can later try to move
"memblock_free()" to a name that isn't so misleading.

Commit 77e02cf57b6c ("memblock: introduce saner 'memblock_free_ptr()'
interface") should hopefully fix that panic that Vlastimil saw, and
the kernel test robot report as well.

And it should make it easy to cleanly fix that 'copy' leak too.
