[PATCH 07/15] mm/page_isolation: use folio_page() in page_is_unmovable()

[Nilay Vaish]

As part of the memdescs effort, struct folio will be allocated
separately from struct page and will no longer overlay the head page.

Replace &folio->page with folio_page(folio, 0) when passing the head
page to compound_order() in page_is_unmovable(). Keep compound_order()
rather than folio_order() since page_is_unmovable() inspects pages
without holding a folio reference.

No functional change intended.
