[PATCH] [MTD] NAND: Wrong calculation of page number in nand_block_bad()

[Knobloch, Thomas]

In case that there is no memory based bad block table available the
function nand_block_checkbad() in drivers/mtd/nand/nand_base.c will call
nand_block_bad() directly. When parameter 'getchip' is set to zero,
nand_block_bad() will not right shift the offset to calculate the
correct page number.
