net/mlx5: Use one completion vector if eth is disabled
If eth is disabled by devlink, use only a single completion vector to
have minimum performance of all users of completion vectors. This also
affects Infiniband performance.
The rest of the vectors can be used by other consumers on a first come
first served basis.
mlx5_vdpa will make use of this to allocate dedicated vectors for its
own use.
