cfg80211: wext: only allow WEP keys to be configured before connected
When not connected, anything but WEP keys shouldn't be allowed to be configured for later - only static WEP keys make sense at this point. Change wext to reject anything else just like nl80211 does. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
