Patch for disabling active probe requests.

In an experiment where I have multiple clients uploading tcp traffic using the OnOffAppplication to an AP, the clients' probe requests continuously synchronize and collide together. I believe this is a known issue addressed by previous bugs. When I tried to disable active probing to prevent this behaviour, no effect was observed, and each client still attempts to send a probe request when it first tries to send data packets. It seems that the flag is not checked at all before attempting to send probe requests. I have a simple patch prepared that should fix this issue. It adds an instance variable that is checked before attempting to send a probe request.
