ipodnano3g: mark the 4-CE Toshiba BA94D598 row checked

Browse source 
A contributor's check archive matches the row exactly and passes both

sectors, test_crash survives 100 power cuts with 0 sectors wrong.

- **BA94D598 x4, 2026-09-20.** A contributor's check archive matches the
row exactly (Toshiba, mode 1, vflspares 201 by our own formula). Clean
