  Eliminate an unnecessary test from vm_fault's delete-behind heuristic.
  Specifically, since the delete-behind heuristic is never applied to a
  device-backed object, there is no point in checking whether each of the
  object's pages is fictitious.  (Only device-backed objects have
  fictitious pages.)
