WPS ER: Make sure PIN timeout does not interrupt PBC operation 

We need to clear the selected registrar timeout from wps_er_learn
when stopping the protocol run at M7 (previously, this was done only
when WSC_Done was being processed). In addition, we need to cancel
the timeout when a new PBC operation is started.
