Currently when marking a block, we use spinand_erase_op() to erase the block before writing the marker to the OOB area. Doing so without waiting for the operation to finish can lead to the marking failing silently and no bad block marker being written to the flash.
In fact we don't need to do an erase at all before writing the BBM. The ECC is disabled for raw accesses to the OOB data and we don't need to work around any issues with chips reporting ECC errors as it is known to be the case for raw NAND.
