cfg80211: don't optimise wext calls too much
In the wext code I tried to not reconnect all the time when the user wasn't really sure what they were doing, like setting the BSSID back to the same value it was. However, this optimisation should only be done while associated so that setting the BSSID back to the same value that it was actually triggers a new association if not currently associated. To achieve, that, put the relevant code into the !IDLE case instead.
