aspeed/hace: Initialize g_autofree pointer

As mentioned in docs/devel/style.rst "Automatic memory deallocation":

* Variables declared with g_auto* MUST always be initialized,
  otherwise the cleanup function will use uninitialized stack memory

This avoids QEMU to coredump when running the "hash test" command
under Zephyr.
