mtd: nand: remove multiplied-by-2 block logic
The parent commit 771c568b ("mtd: nand: add accessors, macros for in-memory BBT") makes the following comment obsolete: /* * Note that numblocks is 2 * (real numblocks) here, see i+=2 * below as it makes shifting and masking less painful */ I don't think it ever could have been "less painful" to have to shift an extra bit (or 2, or 3) at various points in nand_bbt.c (and even outside, since we leak our in-memory format). But now it is certainly more painful, since we have nice macros and functions to retrieve the relevant portions of the BBT. This patch removes any points where the block number is doubled/halved/otherwise-shifted, instead representing the block number in its most natural form: as the actual block number.
