[dts][PATCH V3 3/4] test_plans/kernelpf_iavf: 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.

Signed-off-by: Weiyuan Li <weiyuanx.li@intel.com>

v2:
-fix format issue
v3:
-modify the code to check whether vf-vlan-pruning option exists.
-modify the description of the test plan about vf-vlan-pruning.
