Fix sr check and health check to reopen pool_passwd upon reload.

The streaming replication check and health check process forgot to
reopen pool_passwd upon reload.  If sr_check_passwd or
health_check_passwd is empty string, the password is obtained from
pool_passwd. Thus those process read outdated content of pool_passwd
upon reload.

Backpatch-through: v4.2
