James Prestwood 1491ebe877 auto-t: add SA Query tests
Two autotests:

1. Tests SA Query procedure when the AP goes down. In this case the AP
   goes down ungracefully, now allowing it to send out any deauth
   frames. When the AP comes back up, IWD still thinks its connected.
   The AP will then send unprotected disassociate frames so the client
   can re-connect. This kicks off the SA Query procedure, which the AP
   will not respond to. At this point we can deauth and reconnect to
   the AP.

2. Test SA Query procedure when a disassociate frame has been spoofed.
   In this case we receive an unprotected disassociate frame and start
   SA Query. The AP should then respond to the SA query within the
   timeout. We then know the frame was spoofed and can remain
   connected.
