[pgpool-committers: 7437] pgpool: Fix segfault in snapshot isolation mode.

[Tatsuo Ishii]

Fix segfault in snapshot isolation mode.

If one DB nodes goes down, pgpool segfaulted in the mode. This
happened in si_get_snapshot(). This was caused because it did not
check whether DB node is alive or not.
