ACPICA: fixup after acpi_get_object_info() change
Commit 15b8dd53f5ffa changed info->hardware_id from a static array to
a pointer. If hardware_id is non-NULL, it points to a NULL-terminated
string, so we don't need to terminate it explicitly. However, it may
be NULL; in that case, we *can't* add a NULL terminator.
This causes a NULL pointer dereference oops for devices without _HID.
