Pragaspathi Thilagaraj a97d498743 qcacld-3.0: Send preauth status for SAE hybrid roaming 
For WPA3 SAE LFR-3.0 roaming, authentication is offloaded to the
wpa_supplicant via the host driver due to the target crypto
inavailability limitations. The target does candidate selection
and sends the WMI_ROAM_PREAUTH_START_CMDID to the driver.

Once the SAE authentication is done, the supplicant sends the
external auth NL command with the authentication status, PMKID
derived. On receiving this event, send the PMKID, bssid, auth
status to the target over WMI_ROAM_PREAUTH_STATUS_CMDID command.

The host driver decides if the external authentication event is
received for preauth candidate or for initial connection by
checking the connected state information of the csr session.

When the authentication fails with the first candidate, the
target triggers the preauth start for the next candidate. This
happens till there are no candidates available to roam.

There could be a situation where the firmware sends preauth
event for candidate1 and before the supplicant could send the
external auth command to the host driver, the candidate1 preauth
timer could have expired and firmware sends the preauth start for
second candidate. After SAE is done with second candidate also,
the supplicant sends external auth event for second candidate. So
in this situation the firmware should decide to choose the
latest candidate. The host driver here is a mere passthrough and
doesn't maintain timer for the preauth event for each BSSID to
drop the expired candidate preauth events.
