another wireless crash

another wireless crash

[Ben Greear]

This is what killed my system while I was away from the serial console.

I had around 135 virtual stations running, and they were idle so being
periodically disconnected from the AP for idle-ness.

This is mostly FYI.  I'll re-build with debugging and do some more
testing to try to track these down.
