x86/apic: Add irq_data argument to apic->cpu_mask_to_apicid()
The decision to which CPUs an interrupt is effectively routed happens in
the various apic->cpu_mask_to_apicid() implementations
To support effective affinity masks this information needs to be updated in
irq_data. Add a pointer to irq_data to the callbacks and feed it through
the call chain.
