OneNAND: Update OOB free table

Do not use bytes managed by OneNAND ECC logic for Logical Sector Number data.

---
The OneNAND specification says that the three bytes at offsets 2, 18, 34 and 50 are managed by internal ecc logic. The effect is obvious as modifying these bytes, it also modifies ECC code for spare area.
