The ICH9 PCI device uses qemu_init_irq() in its instance_init method,
but fails to clean it up in its uninit. This results in a leak,
detected by ASAN when running the device-introspect-test:
Direct leak of 96 byte(s) in 1 object(s) allocated from:

We could call qemu_free_irq() in pci_ich9_uninit(), but
since we have a method of initializing the IRQ that doesn't
need manual freeing, use that instead: qemu_init_irq_child().
