mm/huge_memory: simplify pgtable deposit detection
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.
There is no known in-tree workload that triggers this. Mostly a
defensive/simplifying change.
