[PATCH] mm/hugetlb: use account_new_hugetlb_folio() in add_hugetlb_folio()

[Enze Li <lienze@kylinos.cn>]

Every other place that accounts a new huge page already calls
account_new_hugetlb_folio(), and add_hugetlb_folio() was the odd one
out, still open-coding the same two increments.  Swap it over.

The helper is defined further down the file, so add a forward
declaration for it.

No functional change intended.
