[CORE-11271] ACPI hardware IDs not properly null-terminated - ReactOS JIRA

ACPI has the following code snippet:

		index = 0;

		index += swprintf(&temp[index],

							L"ACPI\\%hs",

							Device->pnp.hardware_id);

		index++;

		index += swprintf(&temp[index],

							L"*%hs",

							Device->pnp.hardware_id);

		index++;

		temp[++index] = UNICODE_NULL;

Using ++index in the last line moves the null one further than intended, and temp[index-1] will be left uninitialized
