qcacld-3.0: Cleanup sae auth timer for romaing scenarios

Browse Source 
Host sends SAE auth retry frames if the response/ack for the previous
SAE auth is not received. In roam scenarios like roam abort, HO fail
host don't need to send SAE auth again.
Hence cleanup sae auth timer for roaming scenarios.
