wlan: PMF state not correct after 802.11r roaming

There is a problem where the PMF (Protected
Management Frames, 802.11w) state of the
connection is not correct after a 802.11r (Fast
Transition, FT) roaming operation.  This is fixed
by setting the PMF state correctly during this type
of roaming operation.
