[pgpool-committers: 754] pgpool: Fix child_exit() to not call send_frontend_exits() if there's n

[Tatsuo Ishii]

Fix child_exit() to not call send_frontend_exits() if there's no
connection pool, otherwise it segfaults because send_frontend_exits()
referes to objects pointed to by pool_connection_pool.  This could
happen in worker_child while it tries to do s_do_auth() and it calls
pool_read() failed to read backend socket then calls child_exit().
Per bug track #44.
