Possible solution in r25247. Can't reproduce bug on my system.

Failures (in peer.c:230 for instance) are caused by the peer that is the root of the tunnels receiving traffic on tunnels that are either marked for deletion or already deleted.

Mesh handling of this case has been improved in r25354, mesh detects that the tunnel is no longer usable and just drops and logs the message instead of trying to resend it.

The break_op in gnunet-service-mesh.c:5981 (traffic on unknown tunnel) has been left, but can be demoted to a debug/statistic if necessary.
