wlan: Set negotiated auth type to OPEN for SAE-pmk cache case

propagation from qcacld-3.0 to prima.

wpa_supplicant sends connect request with open auth and pmkid
when PMK caching is enabled and if it has PMK/PMKID cached.
Set rsn_auth_type to SAE when connect request has AKM as SAE
auth_type as open.
Set negotiated auth type to OPEN in SAE with pmk cache case as
open authentication going to happen. Similar fix is applicable
for FT-SAE. Handle the same.
