commit2572cf57d7upstream. The consumers of this routine expects the affinity map of of vector index relative to the first completion vector. The upper layers are not aware of internal/private completion vectors that mlx5 allocates for its own usage. Hence, return the affinity map of vector index relative to the first completion vector.
