James Prestwood bb27cea54c auto-t: release radio/hostapd instances from cls
The cls object is part of the unittest framework and its lifespan
is out of test-runner's control. Setting objects into the cls
object sometimes keeps those objects around longer than desired.
Its best to unset anything set in cls when the test is tore down.
