ide: destroy DMA mappings after ending DMA (v2)
Move ide_destroy_dmatable() call out from ->dma_end method to {ide_pc,cdrom_newpc,ide_dma}_intr(), ide_dma_timeout_retry() and sgiioc4_resetproc(). This causes minor/safe behavior changes w.r.t.: * cmd64x.c::cmd64{8,x}_dma_end() * cs5536.c::cs5536_dma_end() * icside.c::icside_dma_end() * it821x.c::it821x_dma_end() * scc_pata.c::__scc_dma_end() * sl82c105.c::sl82c105_dma_end() * tx4939ide.c::tx4939ide_dma_end() v2: * Fix build for CONFIG_BLK_DEV_IDEDMA=n (reported by Randy Dunlap).
