pgsql: Error out on send failure in walsender loop.

Error out on send failure in walsender loop.

I changed the loop in 9.3 to use "goto send_failure" instead of "break" on
errors, but I missed this one case. It was a relatively harmless bug: if
the flush fails once it will most likely fail again as soon as we try to
flush the output again. But it's a bug nevertheless.

Report and fix by Andres Freund.
