ide: move ide_map_sg() call out of ->dma_setup method (take 2)
Move ide_map_sg() call from ->dma_setup implementations and ide_destroy_dmatable() one from *_build_dmatable() to ide_dma_prepare(). There should be no functional changes caused by this patch. Sergei: Removed 'use_pio_instead' labels and replaced 'goto' with 'return 0' -- that required no changes to the follow-up patches...
