[pgpool-committers: 7386] pgpool: Fix bug child_max_connections is not respected if ERROR occurs.

[Tatsuo Ishii]

Fix bug child_max_connections is not respected if ERROR occurs.

When frontend aborts, the counter for child_max_connections is rewound
because ereport(ERROR) issues long jump. Fix is declaring the variable
with volatile qualifier. This is a long standing bug, probably since
child_max_connections was introduced.
