net/mlx5: fix validation of VLAN PCP item

Function mlx5_flow_validate_item_vlan() validates the user setting
is supported by NIC, using a mask with TCI mask 0x0fff.
This check will reject a flow rule specifying a vlan pcp item.

This patch updates mlx5_flow_validate_item_vlan() to use mask 0xffff,
so flow rules with vlan pcp item are accepted.
