[pgpool-committers: 2393] pgpool: Fix client connection leak.

[Tatsuo Ishii]

Fix client connection leak.

Since 3.4.0 pgpool-II child does not close the connection to client
when it ends the session.  This leads to serious "CLOSE_WAIT" flood,
which makes pgpool-II unusable since no new connection from clients
accepted.  Problem reported by Pablo Sanchez in [pgpool-general:
3394].
