subj causes PCI devices that do not have acpi-index assigned,
having bogus 'PCI Label Id = 0'.
The later triggers another Windows bug that leads to guest hang
in case of localized Windows versions [1].
Workaround is for QEMU to return invalid Package on _DSM(func=7) request
if acpi-index is not configured, which makes Windows ignore returned value
and not assign 'PCI Label Id'.
It should help [1] users to boot localized Windows variants as long as
no PCI devices have acpi-index explicitly assigned.

While this is not a qemu bug fix, this change feels like a good candidate for qemu-stable, - what do you think? I picked it up for current stable series, which are 7.2, 8.2, 9.1 and 9.2.
