net/mlx5: Properly deal with flow counters when deleting rules
When deleting a flow counter, the modify mask should be the action and the flow counter. Otherwise the flow counter is not deleted and we'll get a firmware warning when deleting the remaining destinations on the same FTE. It only happens in the presence of flow counter and multiple vport destinations. If there is only one vport destination, there is no need to update the FTE when deleting the only vport destination, we just delete the FTE.
