mm: page_alloc: pass PFN to __free_pages_bootmem
__free_pages_bootmem prepares a page for release to the buddy allocator
and assumes that the struct page is initialised. Parallel initialisation
of struct pages defers initialisation and __free_pages_bootmem can be
called for struct pages that cannot yet map struct page to PFN. This
patch passes PFN to __free_pages_bootmem with no other functional change.
