Commit cef2e7148e32 ("hw/isa/i82378: Remove intermediate IRQ forwarder")
passes s->cpu_intr to i8259_init() in i82378_realize() directly. However, s-
>cpu_intr isn't initialized yet since that happens after the south bridge's
pci_realize_and_unref() in board code. Fix this by initializing s->cpu_intr
before realizing the south bridge.
