bug #25492 (Invalid deallocation in mysql_stmt_fetch) 

Operating with the prepared statements we don't alloc MYSQL_DATA structure,
but use MYSQL_STMT's field instead (to increase performance by reducing
malloc calls).
So we shouldn't free this structure as we did before.


libmysqld/lib_sql.cc:
  we only should free data->alloc here, as the 'data' is a member
  of STMT structure
