mlx5: fix mlx5_get_vector_affinity to start from completion vector 0
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.
