Subject: [PATCH vhost v3 03/24] vdpa/mlx5: Drop redundant code
Originally, the second loop initialized the CVQ. But (acde3929492b
("vdpa/mlx5: Use consistent RQT size") initialized all the queues in the
first loop, so the second iteration in init_mvqs() is never called
because the first one will iterate up to max_vqs.
