[PATCH bpf v2 6/7] selftests/bpf/test_offload.py: reset ethtool features after failed setting

[Toke Høiland-Jørgensen <toke@xxxxxxxxxx>]

From: Toke Høiland-Jørgensen <toke@xxxxxxxxxx>

When setting the ethtool feature flag fails (as expected for the test), the
kernel now tracks that the feature was requested to be 'off' and refuses to
subsequently disable it again. So reset it back to 'on' so a subsequent
disable (that's not supposed to fail) can succeed.
