Mohammad Tafzeel Shams 7fed014308 MDEV-38140: InnoDB index corruption after UPDATE affecting virtual 
columns

Issue:
- Purge thread attempts to purge a secondary index record that is not
  delete-marked.

Root Cause:
- When a secondary index includes a virtual column whose v_pos is
  greater than the number of fields in the clustered index record, the
  virtual column is incorrectly skipped while reading from the undo
  record.
- This leads the purge logic to incorrectly assume it is safe to purge
  the secondary index record.
- The code also confuses the nth virtual column with the nth stored
  column when writing ordering columns at the end of the undo record.

Fix:
- In trx_undo_update_rec_get_update(): Skip a virtual column only
  when v_pos == FIL_NULL, not when v_pos is greater than the number
  of fields.
- In trx_undo_page_report_modify(): Ensure ordering columns are
  written based on the correct stored-column positions, without
  confusing them with virtual-column positions.
