The new warning originates from acpi_get_override_irq, which I changed to
use helper functions that warn when they fail.
When IOAPICs and ACPI are enabled in a kernel and run on ACPI hardware
that doesn't use the ioapics the pnp acpi code calls this function,
looking for ACPI irq overrides. ACPI irq overrides exist only in the
ioapic case so this function will never succeed. So make the function
fail fast so we don't call into help functions that legitimately
complain when they fail.
