WebView: clean up onReceivedSslError docs

    /**

     * Notify the host application that an SSL error occurred while loading a

     * resource. The host application must call either handler.cancel() or

     * handler.proceed(). Note that the decision may be retained for use in

     * resource. The host application must call either {@link SslErrorHandler#cancel} or

     * {@link SslErrorHandler#proceed}. Note that the decision may be retained for use in

     * response to future SSL errors. The default behavior is to cancel the

     * load.

     * <p>

     * This API is only called for recoverable SSL certificate errors. In the case of

     * non-recoverable errors (such as when the server fails the client), WebView will call {@link

     * #onReceivedError(WebView, WebResourceRequest, WebResourceError)} with {@link

     * #ERROR_FAILED_SSL_HANDSHAKE}.

     * <p>

     * {@link SslErrorHandler#cancel} and never allow proceeding past errors.
