[dts] [PATCH V2 10/10] tests/vf_vlan: update case code for driver change

[Jiale Song]

the iavf vlan priv-flags of the kernel drive of columbiaville has changed from 
vf-vlan-prune-disable to vf-vlan-pruning in ice 1.7.2_3_g03d5f45f,and is closed 
by default,so the affected case needs to modify the code
