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.

Jason prefers jgg-uk2M96/98Pc@public.gmane.org for his upstream work, so might need to
