[PATCH v1] net/mlx5: fix meter creation default state

[Matan Azrad]

From: Rongwei Liu
> Disable means there is no packet drop in the meter. Meter is active always but
> programmed with another CIR/CBS value.
> 
> If the user wants to disable the meter in creation, PMD calls the disable() API
> manually after meter initialized.
> 
> Fixes: 444320186393 ("net/mlx5: support meter creation with policy")
