[DSRM] Do recovery actions only after validation passed once.

Symptom: If there is no live network in the lab, data stall recovery
will be triggered always when validation failed. It might cause lab
testing failed. To avoid it, skipping the recovery action if there's
no any validation pass before.

Solution: Start to do the recovery actions after validation passed once.
