[JFFS2] Add support for write-buffer verification. We've seen some evil corruption issues, where the corruption seems to be introduced after the JFFS2 crc32 is calculated but before the NAND controller calculates the ECC. So it's in RAM or in the PCI DMA transfer; not on the flash. Attempt to catch it earlier by (optionally) reading back from the flash immediately after writing it.
