Remove error report from pq_endmessage when pq_putmessage fails.  The only possible failure is in pq_flush, which will log a (better!) report anyway --- so pq_endmessage is just cluttering the log with a redundant entry.  This matters when a client crashes partway through a large query, since we will emit many broken-pipe reports before finishing the query and exiting.
