The ACPI spec says bit 17 should be used to indicate support
for Generic Initiator Affinity Structure in SRAT, but we currently
set bit 13 ("Interrupt ResourceSource support").

Fix this by actually setting bit 17 when evaluating _OSC.

Fixes: 01aabca2fd54 ("ACPI: Let ACPI know we support Generic Initiator Affinity Structures")
