From: Sagi Grimberg <[email protected]>

commit 2572cf57d75a7f91835d9a38771e9e76d575d122 upstream.

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.
