[RFC PATCH 11/34] mm: vmscan: remove stack copy address of pud pass in wallk_pud_range()

We want to change how pXdp_get() works with generic compile-time folded
page tables. To prepare for that, replace passing the address of a stack
copy of a pXd to walk_pmd_range() with pud pointer directly so that
the ignoring the value of folded entries.

There should be no functional change.
