[Ovmsdev] WiFi mode off reboot

Hi folks,

Another crash.  Not repeatable, but wanted to report it before I head up
stairs to end the day.

I had booted the module, modem off, obdii ecu started, v2 server enabled
but not connected.  Wifi was started but the local network is hidden, so
it wasn't connected.  This is all in the startup event script.  OBDWiz
dongle running, all fine.  The plan was to let it run for the night, to
catch any longer-term reboots, so I needed to turn off the wifi in order
to keep the screen from filling up with 'incorrect scan type' messages. 
Hit wifi mode off, and it crashed (see below).  Doesn't appear to be a
memory issue.  Tried it a second time, and wifi stopped as normal. 

{sigh}  Definitely time for bed...

Greg
