Zi Yan aa5fe31b6b mips: use nth_page() in place of direct struct page manipulation ...

__flush_dcache_pages() is called during hugetlb migration via
migrate_pages() -> migrate_hugetlbs() -> unmap_and_move_huge_page() ->
move_to_new_folio() -> flush_dcache_folio().  And with hugetlb and without
sparsemem vmemmap, struct page is not guaranteed to be contiguous beyond a
section.  Use nth_page() instead.

Without the fix, a wrong address might be used for data cache page flush.
No bug is reported. The fix comes from code inspection.
