qcacld-3.0: Update CSR session PMK during Roam Sync Propagation

Currently CSR session PMK is updated from the set_key command from
supplicant after successful 8 way handshake with the AP. However,
in case of roaming to an AP which already has the PMKID cached, the
Roam Sync happens with Auth Status Authenticated and set_key from the
supplicant does not happen. In this case, the value in the CSR session
PMK is incorrect and is the PMK of the previous AP before roaming.
After this scenario, if any RSO command is sent to the FW, the incorrect
PMK is sent as part of the RSO command updating the FW with incorrect
PMK for the current AP. The next time a roaming happens to the same AP,
then the 4 way handshake fails and fallback to 8 way handshake happens.

Update the PMK in CSR session for the current AP from PMKID cache
during Roam Sync propagation, if the Auth Status is authenticated.
