[PATCH v7 13/23] net/mlx5e: Have mdev pointer directly on the icosq structure

Aurelien Aptel

From: Or Gerlitz <ogerlitz@nvidia.com>

This provides better separation between channels to ICO SQs for use-cases
where they are not tightly coupled (such as the upcoming nvmeotcp code).

No functional change here.
