Allow non-WPA IEEE 802.1X to be select even if WPA is also enabled

If key_mgmt was set to allow both WPA and non-WPA IEEE 802.1X (i.e., to
IEEE8021X WPA-EAP), non-WPA IEEE 802.1X was rejected while preparing
association parameters. Allow this special case to be handled by
selecting non-WPA case if the scan results for the AP do not include
either WPA or RSN elements.
