Subject: [PATCH]connection: avoid crash when CloseWellKnownConnections() gets called twice
Patch-mainline: to be upstreamed
Git-commit: 74472c4e8e4c873014554f321ec2086066126297
Git-repo:

CloseWellKnownConnections() closes all connections and deallocates
their data. Thus all entries in ListenTransConns are invalid.
To avoid access to those entries set ListenTransCount to 0.
This avoids crashes when CloseWellKnownConnections() is called twice
for instance when FatalError() is called on Xserver shutdown.
