[pgpool-committers: 10214] pgpool: Fix authentication failure after updating pool_passwd and reloa

[Tatsuo Ishii]

Fix authentication failure after updating pool_passwd and reload.

If pool_hba.conf is disabled, updating pool_passwd was not recognized
by pgpool child process even if pgpool reload was performed.  The
reload processing function check_config_reload() mistakenly assumed
that reopening pool_passwd was only necessary when enable_pool_hba is
on.

Backpatch-through: v4.1
