In case of 4way handshake offload, transition disable policy
updated by the AP during EAPOL 3/4 is not updated to the cfg80211
layer. This results in mismatch between transition disable policy
between the upper layer and the driver. This patch addresses this
issue by updating transition disable policy as part of port
authorization indiation.
