ctdb-server: Avoid removing connections for released IP

ctdb-server: Avoid removing connections for released IP

Commit c6602b686b4e50d93272667ef86d3904181fb1ab causes TCP connections
to be cleared whenever an associated client goes away.  This shouldn't
happen when the associated public IP is being released, since the
takeover node will need the connection details to send tickle ACKs.

Sorry, I missed this when reviewing that commit.
