Well, this is not exactly a cleanup, it's needed because of the
rework done in patch 2: we no longer want the for loop to automatically
increment the chip variable (if we fail to write the BBT on a specific
die, we retry until we succeed or run out of free valid erase blocks).

Now, if you really want to make it part of patch 1, at least explain
why you're doing that (in preparation of BBT write failure handling).

Note that I don't want you to completely drop this change, just put it
back in patch 2 or explain why you're doing it in patch 1 in your commit
message.
