ide-atapi: start DMA after issuing a packet command
upstream commit: 2eba08270990b99fb5429b76ee97184ddd272f7f Apparently¹, some ATAPI devices want to see the packet command first before enabling DMA otherwise they simply hang indefinitely. Reorder the two steps and start DMA only after having issued the command first.
