Whether a PMD has a deposited PTE page table only depends on whether the
architecture requires deposits or the VMA is anonymous.

Implement this rule directly in vma_has_deposited_pgtable(), avoiding
mistaking a non-anonymous raw PFN PMD for one with a deposit and attempting
to withdraw a page table that was never deposited.
