ide: call ide_build_sglist() prior to ->dma_setup (v2)
* Re-map sg table if needed in ide_build_sglist(). * Move ide_build_sglist() call from ->dma_setup to its users. * Un-export ide_build_sglist(). v2: * Build fix for CONFIG_BLK_DEV_IDEDMA=n (noticed by Randy Dunlap). There should be no functional changes caused by this patch. Cc: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
