FT: Do not try to use FT-over-air if reassociation cannot be used

There is no point in going through FT authentication if the next step
would have to use association exchange which will be rejected by the AP
for FT, so only allow FT-over-air if previous BSSID is set, i.e., if
reassociation can be used.
