nl80211: Fix WPA_VERSIONS attribute for Connect command

Browse source 
The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().
