Just wanted to let everyone know that I'll need to work on a bit better
solution.

The reason is that LEB does not have to start at the max_write_size
boundary, and my v2 does not take that into account. Although for CFI
NOR case this should not matter, because LEB starts at offset 128 (UBI
headers take 64 bytes each). However, this might matter on some other
flash.
