Amaury Denoyelle 27ff7ff296 BUG/MEDIUM: conn: fix UAF on connection after reversal on edge
When a connection is reversed, some elements must be resetted prior to
reusing it. Most notably, connection must be removed from lists specific
on frontend/backend sides.

When reverse was performed for frontend to backend side, connection was
not removed via its <stopping_list> attach point. On previous releases,
this did not cause any issue. However, crashes start to occur recently,
probably due to the recent reorganization of connection list attach
points from the following patch.

  commit a96f1286a7
  BUG/MINOR: connection: rearrange union list members

To fix this, simply ensure that <stopping_list> detach is performed via
conn_reverse().

This patch must be backported up to 3.0 release.
