Devlink features were introduced to disallow devlink reload calls of userspace before the devlink was fully initialized. The reason for this workaround was the fact that devlink reload was originally called without devlink instance lock held. However, with recent changes that converted devlink reload to be performed under devlink instance lock, this is redundant so remove devlink features entirely. Note that mlx5 used this to enable devlink reload conditionally only when device didn't act as multi port slave. Move the multi port check into mlx5_devlink_reload_down() callback alongside with the other checks preventing the device from reload in certain states.
