That's a tricky situation. The controller's firmware prevents booting, so you can't fix things. 🙁

Questions to the PC/XT people:
Would it be possible to remove the ROM chip of that controller and re-insert it after post ?
If so, would the low-level routine still be accessible and functional, even though the PC BIOS didn't check the Option-ROM during POST ?

It works! I managed to boot from the IBM XT utilities floppy and perform a low-level format on the drive. The error is gone and the drive works.
