Add a struct irq_affinity pointer to the find_vqs methods, which if set is used to tell the PCI layer to create the MSI-X vectors for our I/O virtqueues with the proper affinity from the start. Compared to after the fact affinity hints this gives us an instantly working setup and allows to allocate the irq descritors node-local and avoid interconnect traffic. Last but not least this will allow

These changes were as in linux-next as e1c287efcd4cf688564ed1112d032b5dac29b159 - I tweaked the commit log slightly. Too many people were complaining of warnings and errors in virtio so I decided revert is the safest path forward right now.

Some vqs may not need to be allocated when their related feature bits are disabled. So callers may pass in such vqs with "names = NULL". Then we skip such vq allocations.

Install the callbacks via the state machine. The driver supports multiple instances and therefore the new cpuhp_state_add_instance_nocalls() infrastrucure is used. The driver currently uses get_online_cpus() to avoid missing a CPU hotplug event while invoking virtnet_set_affinity(). This could be avoided by using cpuhp_state_add_instance() variant which holds the hotplug lock and invokes callback
