hostapd: fix 11r defaults when using WPA

Browse Source 
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.
