RSN: Stop 4-way handshake if scan results are not available

Browse Source 
While there may have initially been cases where the RSNE from
Beacon/Probe Response frames was not available from some drivers, it is
now more valuable to notice if such a case were to be hit with drivers
that are always expected to have such information available. As such,
make it a fatal error if the scan results for the current AP are not
available to check the RSNE/RSNXE in EAPOL-Key msg 3/4.
