[PATCH 05/15] mm/hugetlb_cma: use folio_page() in hugetlb_cma_free_frozen_folio()

[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.

Pass folio_page(folio, 0) instead of &folio->page to
cma_release_frozen() in hugetlb_cma_free_frozen_folio().

No functional change intended.
