mm/debug_vm_pgtable: use struct pgtable_debug_args in PUD modifying tests

This uses struct pgtable_debug_args in PUD modifying tests.  The allocated
huge page is used when set_pud_at() is used.  The corresponding tests are
skipped if the huge page doesn't exist.  Besides, the following unused
variables in debug_vm_pgtable() are dropped: @prot, @paddr, @pud_aligned.
