[pgpool-committers: 7637] pgpool: Fix verify_backend_node_status().

[Tatsuo Ishii]

Fix verify_backend_node_status().

It is possible that backend_hostname is Unix domain socket but
wal_receiver connects via TCP/IP localhost.
verify_backend_node_status() should accept this as normal.  This
actually happened in the Pgpool-II cluster created by pgpool_setup.  I
found this while testing detach_false_primary.
