net/mlx5: fix mark action with drop action

Marking a packet which will not be received by the NIC is useless, even
if this action remains possible, it blocks the creation of the flow
counter which embed a mark action to a drop queue to be created.

Fixes: 31ba9997f11a ("net/mlx5: fully convert a flow to verbs in validate")
