[PATCH v2] net/mlx5/hws: fix VLAN item handling on non relaxed mode

[Bing Zhao]

From: Hamdan Igbaria <hamdani at nvidia.com>

If a VLAN item was passed with null mask, the item handler would
return immediately and thus won't set default values for non relax
mode.
Also change the non relax default set to single-tagged (CVLAN).
