  Bug #28430 Failiure in replication of innodb partitiitioned tables on row/mixed format.
  
  In the ha_partition::position() we didn't calculate the number
  of the partition of the record. We used m_last_part value
  instead, relying on that it is set in other place like
  previous call of ::write_row() or something.
  In replication, we do neither of these calls before ::position()
  Delete_rows_log_event::do_exec_row calls find_and_fetch_row
  there in the case of InnoDB partitions have HA_PRIMARY_KEY_REQUIRED_FOR_POSITION
  so use position() / rnd_pos() calls to fetch the record.
  Fixed by adding partition_id calculation to the ha_partition::position()
