Philippe Mathieu-Daudé 521b97cd4e util/vfio-helpers: Pass Error handle to qemu_vfio_dma_map()
Currently qemu_vfio_dma_map() displays errors on stderr.
When using management interface, this information is simply
lost. Pass qemu_vfio_dma_map() an Error** handle so it can
propagate the error to callers.
