Fix primary node detection logic.

There's a possibility that primary node is not detected. This happens
in following situation.  node 0: primary, node 1: standby. Node 0 goes
down. Health checking detects the fact but local status is not updated
yet. Primary node finding (find_primary_node) runs. Node 0's status is
yet healthy. Because find_primary_node fails to connect to node 0, it
immediately returns -1 and fails to find that fact that node 1 is now

Fix is just continuing to look for primary node when fails to connect
to a node.

Per [pgpool-general: 2409].
