    MDEV-12019 FLASHBACK: Server crashes in bitmap_bits_set / pack_row / ...
    
    Reason for this crash is that table->rpl_write_set is NULL. In
    Rows_log_event::do_apply_event we set table->rpl_write_set equal to
    table->write_set. But we do not set table->rpl_write_set in
    Old_rows_log_event::do_apply_event.
