[#MDEV-13401] Assertion failure during main.partition test run

To reproduce, use a debug build of the 10.2-spider branch and run the main.partition test.

The following assertion fails in ha_partition::handle_ordered_index_scan(), at ha_partition.cc:7076, called from ha_partition::multi_range_read_next():

DBUG_ASSERT(i == uint2korr(part_rec_buf_ptr));
