net/mlx5e: TC, ignore match level for post meter rules 

The post meter table only matches on reg_c5. As such, the inner/outer
match levels are irrelevant for the match critieria. The cited patch only
sets the outer criteria to none, thus setting the inner match level for
encapsulated packets. This caused rules with police action on tunnel
devices to not find an existing flow group for the match criteria, thus
failing to offload the rule.

Set both the inner and outer match levels to none for post_meter rules.
