ide: cleanup ide_set_dma()
* ->dma_off_quietly is always called before ide_set_dma()
so the call can be moved inside ide_set_dma().
* ide_dma_check() doesn't touch hardware so ->dma_off_quietly
call for 'rc == -1' case is redundant, remove it.
* '0' and '-1' are the only values returned by ide_dma_check()
so remove dead code for other cases.
There should be no functionality changes caused by this patch.
