Until we use a big hammer and reset the LDC channel of that peer, we
_absolutely_ should not reorder traffic and send to non-stuck peers.

A networking stack should avoid packet reordering in all cases when it
has the ability to do so, and sending packets which came in later to
unstuck peers when there are older packets still pending to the stuck
peer violates that requirement.
