[Stable-7.2.4 30/43] aspeed/hace: Initialize g_autofree pointer |

From: Cédric Le Goater <clg@kaod.org>
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.
