patch

Bug I found in my ns-3.2 tree, race condition problem:
1. STA sends AssocReq

2. STA receives beacon from a different AP from the one it is trying to associate
 2.1 STA calls SetBssid to modify its own bssid to the beacon bssid

3. STA receives AssocResp from the correct AP, but thinks it is associated with the AP that sent the beacon in 2.

so, you have two APs which advertise the same SSID ?
