RSN+WPA: Fix RSNE removing in EAPOL-Key msg 3/4 when RSNXE is included
When the AP advertised RSNE, RSNXE, and WPA IE, hostapd incorrectly removed the RSNE in the EAPOL-Key msg 3/4 if the STA associates with WPA, leaving only RSNXE instead of WPA IE. WPA STA fails to connect to such AP as the WPA IE is missing. Since RSNXE is not really used in non-RSN connection, just remove it here with RSNE.
