iommu/amd: Make sure dma_ops are set for hotplug devices

commit c2a2876e863356b092967ea62bebdb4dd663af80 upstream.

There is a bug introduced with commit 27c2127 that causes
devices which are hot unplugged and then hot-replugged to
not have per-device dma_ops set. This causes these devices
to not function correctly. Fixed with this patch.
