[PATCH v4 25/38] docs/devel/qom.rst: Correct code style

[Alex Bennée]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Per commit 067109a11c ("docs/devel: mention the spacing requirement
for QOM"):

  For a storage structure the first declaration should always be
  called “parent_obj” and for a class structure the first member
  should always be called “parent_class”

Adapt the QOM rST document accordingly.
