ide: cleanup ide_setup_dma()
* There is no need to call ide_release_dma_engine(). * Move the code up to (and including) ide_allocate_dma_engine() call to the callers of ide_setup_dma(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
