    hostapd: fix 11r defaults when using WPA
    
    802.11r can not be used when selecting WPA. It needs at least WPA2.
    
    This is because 802.11r advertises FT support in-part through the
    Authentication and Key Management (AKM) suites in the Robust
    Security Network (RSN) Information Element, which was included in
    the 802.11i amendment and WPA2 certification program.
    
    Pre-standard WPA did not include the RSN IE, but the WPA IE.
    This IE can not advertise the AKM suite for FT.
