[MTD] mtd_dataflash: Incorrect compare-after-write check

After writing to a Dataflash page, the built-in compare operation is
used to check that the page was successfully written.  A logic bug in
checking the results of the comparison currently causes the compare to
never fail.

This bug was originally in the legacy at91_dataflash.c driver.
