4 years agonet/mlx5: fix VLAN PCP item calculation

net/mlx5: fix VLAN PCP item calculation

The VLAN 16 bits tci field contains both values of PCP and VID. When
extracting any one of them - it is required not to affect the other one.
Previous to this commit in routine flow_dev_get_vlan_info_from_items()
we calculated the PCP as follows:
    (1) vlan->vlan_tci &= MLX5DV_FLOW_VLAN_PCP_MASK;
    (2) vlan->vlan_tci |= <3 bits value of PCP>
In line (1) we should have used the negated mask ('~' operator) such
that only the PCP bits will be nullified before ORing them with the
updated PCP value.
