mm/mempolicy.c: get rid of duplicated check for vma(VM_PFNMAP) in queue_pages_range()

This check was introduced as part of
   6f4576e3687 ("mempolicy: apply page table walker on queue_pages_range()")

which got duplicated by
   48684a65b4e ("mm: pagewalk: fix misbehavior of walk_page_range for vma(VM_PFNMAP)")

by reintroducing it earlier on queue_page_test_walk()
