Subtle change to make None.__class__ work:

- descrobject.c:descr_check(): only believe None means the same as
  NULL if the type given is None's type.

- typeobject.c:wrap_descr_get(): don't "conventiently" default an
  absent type to the type of the object argument.  Let the called
  function figure it out.
