[pgpool-committers: 4648] pgpool: Fix pcp_detach_node hung when -g option is specified.

[Tatsuo Ishii]

Fix pcp_detach_node hung when -g option is specified.

"pcp_detach_node -g" had been broken since 3.7. The cause was a misuse
of degenerate_backend_set_ex(). Because of this, actual failover
request was not sent to the pgpool main process. As a result,
pcp_worker process waited vainly for a signal arriving from the
process.

Per bug 391. Problem reported by Tomoyuki Sato, fix by me.
