atheros: Fix hapd_deinit() handler with generic IEs set

Browse Source 
atheros_set_opt_ie() needs to be called before freeing drv->wpa_ie to
avoid hitting double-free on the deinit path. Similarly,
drv->wps_beacon_ie and drv->wps_probe_resp_ie could have been used after
being freed. Fix these be moving the atheros_set_opt_ie() call in
atheros_deinit().
