Bug#59297: Can't find record in 'tablename' on update inner join

Browse Source 
Regression introduced in bug#52455. Problem was that the
fixed function did not set the last used partition variable, resulting
in wrong partition used when storing the position of the newly
retrieved row.

Fixed by setting the last used partition in ha_partition::index_read_idx_map.
