Add WPA-None support:

* WPA-None requires ap_scan=2:
  The major difference between ap_scan=1 (default) and 2 is, that no
  IEEE80211_IOC_SCAN* ioctls/functions are called, though, there is a
  dependency on those. For example the call to wpa_driver_bsd_scan()
  sets the interface UP, this never happens, therefore the interface
  must be marked up in wpa_driver_bsd_associate(). IEEE80211_IOC_SSID
  also is not called, which means that the SSID has not been set prior
  to the IEEE80211_MLME_ASSOC call.
* WPA-None has no support for sequence number updates, it doesn't make
  sense to check for replay violations..
* I had some crashes right after the switch to RUN state, issue is
  that sc->sc_lastrs was not yet defined.
