drbd: only reset online-verify start sector if verify completed
For network hickups during online-verify, on the next verify triggered, we by default want to resume where it left off. After any replication link interruption, there will be a (possibly empty) resync. Do not reset online-verify start sector if some resync completed, that would defeats the purpose. Only reset the start sector once a verify run is completed. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
