For FT-FILS AKM, 1st connection to an AP in a realm takes place
with Full EAP. 2nd connection to any AP in the realm does the
FT initial mobility domain association with authentication
algorithm as FILS. Subsequent connection/roam happens with
FT protocol.
fils_ft key is derived during 2nd connection. But driver
copies from fils_ft buffer after 1st connection is complete
to fill the PMK in the 11r TLV. This causes the pmk len = 0
is sent in the 11r TLV.
Fill the initial connection PMK in RSO command after 1st
connection. From 2nd connection onwards fill the fils_ft.
