[ios] Do not reset SSL status if load was cancelled.

[ios] Do not reset SSL status if load was cancelled.

SSL status needs to be reset if navigation fails with error. But
back-forward navigation calls navigation failure callback with
"cancelled" error. In this case SSL status should not be changed.

The other case where navigation failure callback is called with
cancelled error is load cancellation which should not reset SSL status
as well.
