[pgpool-committers: 7998] pgpool: Fix pgpool_setup to do nothing when no new main node is availab

[Tatsuo Ishii]

Fix pgpool_setup to do nothing when no new main node is available.

When no new main node is available due to there's only 1 node
remaining, pgpool_setup tried to promote a node with node id -1.  This
is impossible. Fix is just skipping whole failover process if new main
node id is -1.
