ide: move command related fields from ide_hwif_t to struct ide_cmd
* Move command related fields from ide_hwif_t to struct ide_cmd. * Make ide_init_sg_cmd() take command and sectors number as arguments. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
