Revert "mtd: spinand: Fix OOB read" 

This reverts stable commit baad618d07.

This commit is adding lines to spinand_write_to_cache_op, wheras the upstream
commit 868cbe2a6dcee451bd8f87cbbb2a73cf463b57e5 that this was supposed to
backport was touching spinand_read_from_cache_op.
It causes a crash on writing OOB data by attempting to write to read-only
kernel memory.
