This really needs to be done to many more autotests but since this
one seems to have random failures ensure that all the tests still
run if one fails. In addition add better cleanup for hwsim rules.
This adds another radio so IWD hits the FT failure path after
authentication to the first BSS fails. This causes a wiphy work
item to be rescheduled which previously was unsafe.
During investigation another separate crash was found. The original is
caused by a disconnect event coming in after a neighbor report scan
was completed (roam failed) during the full roam scan.
The second crash is caused by a disconnect coming in during a full
roam scan when no neighbor report scan was ever issued.
