[dts][PATCH V2 2/4] tests/vf_vlan: update dts code for driver change

[Weiyuan Li <weiyuanx.li@intel.com>]

The out-tree driver has vf-vlan-pruning option,but in-tree driver has
not. So we need different action to enable vlan filter when we validate
the vlan filter function with in-tree and out-tree kernel drvier.
