[pgpool-committers: 7316] pgpool: Fix "no watchdog configuration for local pgpool node" error.

[Tatsuo Ishii]

Fix "no watchdog configuration for local pgpool node" error.

If watchdog is disabled and wd_port is not defined (thus it's 0, which
is the default config value), the error occurred while checking
configured watchdog nodes. If watchdog is disabled, the check should
not be performed. Back patch to V4.2 stable when watchdog local node
was introduced.

Branch
------
