Subject: [PATCH net-next 2/4] net/mlx5: Delete redundant default assignment of runtime devlink params

From: Shay Drory <shayd@...dia.com>

Runtime devlink params always read their values from the get() callbacks.
Also, it is an error to set driverinit_value for params which don't
support driverinit cmode. Delete such assignments.

In addition, move the set of default matching mode inside eswitch code.
