Fix broken authentication for Pgpool's internal connections

The issue is caused by a  mistake in "SCRAM and Certificate authentication
support" commit.
The problem is while authenticating against backend in connection_do_auth(), it
returns to caller as soon as backend returns auth ok response.  So
authentication itself established fine. However connection_do_auth()
does not proceed until it receives "Ready for query", it is required
according to the frontend/backend protocol.
The fix is to keep processing the data after receiving auth_ok response
until we get ready for query.

Patch provided by Tatsuo Ishii <ishii at sraoss.co.jp> and a tiny modification
made by me
