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.
The FT-over-DS test was allowed to fail as it stood. If FT-over-DS
failed it would just do a normal over-Air transition which satisfied
all the checks. To prevent this Authenticate frames are blocked after
the initial connection so if FT-over-DS fails there is no other way
to roam.
