A fix for Bug#14845 "mysql_stmt_fetch returns MYSQL_NO_DATA when
COUNT(*) is 0" (the test case has been pushed already)
sql/sql_cursor.cc:
Fix a return of an unitialized variable: return_zero_rows
checks the return value of send_fields and in case it's 1
doesn't call send_data. This caused creation of an empty result
set for the case when there is a cursor against a select with a
group function and no matching rows.
