ide: use ide_destroy_dmatable() instead of pci_unmap_sg() (take 2)
Use ide_destroy_dmatable() in: * ide-dma.c::ide_build_dmatable() * sgiioc4.c::sgiioc4_build_dma_table() * pmac.c::pmac_ide_{build,destroy}_dmatable() There should be no functionality changes caused by this patch. v2: * pmac.c build fix from Andrew Morton.
