net/mlx5: fix VLAN inner type matching on DR/DV

[ upstream commit b12c7b2 ]

The rte_flow_item_vlan has the inner_type, which is missing on
DR/DV flow engine.

By adding this support, the example testpmd commands could be:

 - matching all vlan traffic with id 2:

 testpmd> flow create 0 ingress pattern eth / vlan vid is 2 / end
          actions queue index 2 / end

 - matching all ipv4 traffic in vlan with id 2:

 testpmd> flow create 0 ingress pattern eth / vlan vid is 2
          inner_type is 0x0800 / end actions queue index 2 / end

Fixes: fc2c498 ("net/mlx5: add Direct Verbs translate items")
