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.
