Fast BSS Transition (802.11r) cannot be performed without driver support for
Station Management Entity (SME). However, wpa_supplicant will select FT suites
(FT-PSK and FT-EAP) even when the driver does not support it. This change has
wpa_supplicant select the FT suites only if the driver supports SME.
