net: microchip: sparx5: Clear rule counter even if lookup is disabled

The rule counter must be cleared when creating a new rule, even if the VCAP
lookup is currently disabled.

This ensures that rules located in VCAPs that use external counters (such
as Sparx5 IS2 and ES0) will have their counter reset even if the VCAP
lookup is not enabled at the moment.
