[dts] [PATCH V1] tests/TestSuite_kernelpf_iavf.py:An abnormal exit needs to execute the same command as a normal exit.

[Tu, Lijuan]

Tear_down will be executed whatever the case is successful or failure. Every case will start from set_up and end with tear_down.
So I don't think it's reasonable to have this patch.

Another sighting, it's better to get current "trust setting" before you change it, and then restore it after your testing.
