[pgpool-committers: 724] pgpool: Fix reaper() not to exit wait3() loop when catches pcp or worke

[Tatsuo Ishii]

Fix reaper() not to exit wait3() loop when catches pcp or worker child
exit event. Otherwise reaper() mistakenly ignore some process exit
event and make a risk of creating zombie process and forgetting to
create new process.  Commit a99744560f54f6723799408cd3623a73b2b335e6
should be enough for pcp child case, but not enough for worker process
case. Problem reported and fix suggested by Goto in
[pgpool-general-jp: 1123].
