[PATCH] mm: use proper PTE accessor in move_ptes()

[Alexander Gordeev]

Follow the pattern established by commit c33c794828f2
("mm: ptep_get() conversion") and use the proper PTE
accessor instead of a direct pointer dereference.

Fixes: b36b701bbcd9 ("mm: expose abnormal new_pte during move_ptes")
