Devices that does not use managed affinity can not export a vector
affinity as the consumer relies on having a static mapping it can map
to upper layer affinity (e.g. sw queues). If the driver allows the user
to set the device irq affinity, then the affinitization of a long term
existing entites is not relevant.
For example, nvme-rdma controllers queue-irq affinitization is determined
at init time so if the irq affinity changes over time, we are no longer
aligned.
