[PATCH 04/10] mm/bootmem_info: allow calling free_bootmem_page() on pages without a bootmem_type

["David Hildenbrand (Arm)" <david@kernel.org>]

As preparation for further changes, let's temporarily allow freeing
pages that were not previously registered.

This will allow freeing unregistered vmemmap pages allocated during boot
through free_bootmem_page() from hugetlb code, until we fully rip all
of that out.
