dispatcher: Not possible to deactivate probing of destination by reload

If ds_probing_mode is set to 3, flag in the dispatcher entry needs to include 8 for probing to happen.

Changing a destination to not include this anymore while the destination do not respond to OPTIONS will cause the probing flag to be re-added because of the delayed response. A restart will fix it.

We need to check against the probing flag in the CB function to determine if we should continue probing this destination. If probing is deativated while waiting for a reply, we should abort.
