mac80211: free ifsta->extra_ie and clear IEEE80211_STA_PRIVACY_INVOKED



I'm not sure if this is best choice, someone might have better
solutions. But this patch fixed the connection problem when switching
from a WPA enabled AP (using wpa_supplicant) to an open AP (using
iwconfig). The root cause is when we connect to a WPA enabled AP,
wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
stop wpa_supplicant and connect to an open AP with iwconfig, there is
no way to clear the extra_ie so that mac80211 keeps connecting with that.

Someone could argue wpa_supplicant should clear the extra_ie during
its shutdown. But mac80211 should also handle the unexpected shutdown
case (ie. killall -9 wpa_supplicant).
