mtd: nand: remove multiplied-by-2 block logic
The parent commit 771c568bcf915e708ae819ef9d07d862f7e2da86 ("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.
