kernel: fix mtd partition erase < parent_erasesize writes
This bug applied where mtd partition end address,
or erase start address, was not cleanly divisible by parent mtd erasesize.
This error would cause the bits following the end of the partition
to the next erasesize block boundary to be erased,
and this partition-overflow data to be written to the partition erase
address (missing additional partition offset address)
of the mtd (top) parent device.
Fixes: FS#2428
