> Flow validation function includes, after all items and actions are validated

> This patch removes the invalid check from validation function.
> Check is incorrect, action_flags bit map is checked against items mask
> MLX5_FLOW_LAYER_TUNNEL.
> Check is also redundant, because VLAN push/pop actions can be used
> together with packet reformat actions.
