[PATCH] Documentation: kunit: Fix KUNIT_DEFINE_ACTION_WRAPPER() argument order

[Kees Cook]

The macro is

#define KUNIT_DEFINE_ACTION_WRAPPER(wrapper, orig, arg_type) ...

so it defines "wrapper" which calls orig(arg_type). The example names
them the other way round. Swap the two order.

You should do this in preference to manually casting to the ``kunit_action_t`` type,
