[dts][PATCH V1] tests/ice_iavf_fdir.py ensure that the environment can be cleaned up after an exception occurs in the case

[Hongbo Li]

1.If testcase throws an exception, the vf will not be cleaned, and cause other cases to fail.
2.Ensure that all sessions exit before deleting vf by adjusting the cleaning environment order.
