From: "Saleem, Shiraz" <shiraz.saleem@xxxxxxxxx>
The consumer of ib_get_vector_affinity API, like nvme-rdma
has an underlying assumption that the device IRQ
affinity are immutable by user and are managed affinity
based, which is not the case for i40iw.
Remove support for this API in i40iw
Fixes: 7e952b19eb63 ("i40iw: Implement get_vector_affinity API")
