BUG#23383: mysql_affected_rows() returns different values than

Browse Source 
mysql_stmt_affected_rows()

The problem was that affected_rows for prepared statement wasn't updated
in the client library on the error.  The solution is to always update
affected_rows, which will be equal to -1 on the error.
