patch to solve crash

great catch, so io_apic code assumes all irqs descriptors belong to a io_apic
irq chip, and that all chip_data is of type irq_cfg.

This patch checks that the interrupt belongs to ioapic before touching chip
data.

With this patch device boots, but graphics probing fails because the legacy
interrupt it wants is reserved.
