[pgpool-committers: 5950] pgpool: Fix segfaut in streaming replication check process.

[Tatsuo Ishii]

Fix segfaut in streaming replication check process.

In case of failure of pg_stat_replication() call, the streaming
replication check process unconditionally tried to free the allocated
memory.  This should only be done when the call succeeds.
