mm/thp: rename pmd_to_page() as pmd_pgtable_page()
Current pmd_to_page(), which derives the page table page containing the
pmd address has a very misleading name. The problem being, it sounds
similar to pmd_page() which derives page embedded in a given pmd entry
either for next level page or a mapped huge page. Rename it as
pmd_pgtable_page() instead.
