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