ctdb-daemon: Don't delete connection information for released IP

As per the comment:

  If the IP address is hosted on this node then remove the connection.

  Otherwise this function has been called because the server IP
  address has been released to another node and the client has exited.
  This means that we should not delete the connection information.
  The takeover node processes connections too.

This doesn't matter at the moment, since the empty connection list for
an IP address that has been released will never be pushed to another
node.  However, it matters if the connection information is stored in
a real replicated database.
