[PATCH 11/39] mtd: nand: denali: increment ecc_stats.failed by one per error

[Masahiro Yamada]

If the addressed page is not erased, the two calls of is_erase()
will both return false, then mtd->ecc_stats.failed will be
incremented by two.  Rather, increment it by one because the whole
page including OOB area is transferred in one transaction.
