Subject: [net-next V2 11/15] net/mlx5: Move devlink registration before mlx5_load

From: Eli Cohen <elic@...dia.com>

In order to allow reference to devlink parameters during driver load,
move the devlink registration before mlx5_load. Subsequent patch will
use it to control the number of completion vectors required based on
whether eth is enabled or not.
