qcacld-3.0: If association timeout send deauth to cleanup the peer session

qcacld-2.0 to qcacld-3.0 propagation

In the scenario where association times out because device has missed
the assoc resp sent by peer, the peer assumes the device to be
connected and thus when device again sends the auth for fresh
connection the peer sends deauth. Thus fresh connection also fails.

To avoid this send deauth after association time out, to cleanup
the session in peer.
