qcacld-3.0: Update authentication algo in SAE auth retry frame

Browse source 
In SAE pmksa caching case, the authentication algorithm will be
open and pmkid will be included in association request frame.
Full SAE authentication with auth algo 3 will not happen.
If in SAE pmksa caching case, the auth frame is not acknowledged
then auth retry happens and while filling the authentication
algorithm in the auth retry frame, the driver doesn't check if
sae pmk caching is used. So if auth retry happens due to auth
failure, the driver sends authentication frame with auth algo as
SAE. So the AP tries to validate the auth frame for SAE cyclic
group and sends auth reject with status code 77 - the offered
finite cyclic group is not supported.

Fill the authentication algorithm as open for auth retry frame
in sae pmk cached case.
