[pgpool-committers: 10556] pgpool: Fix heartbeat_device treatment.

[Tatsuo Ishii]

Fix heartbeat_device treatment.

While processing pgpool.conf, heartbeat_device was mistakenly treated
and the first device was ignored. For example:

heartbeat_device0 = 'eth0'

the configuration process disregarded 'eth0' and acted as if no device
was set. Another example:

heartbeat_device0 = 'eth0;eth1'

"eth0" was simply ignored.
