Alexander Potapenko 88938359e2 virtio: kmsan: check/unpoison scatterlist in vring_map_one_sg() 
If vring doesn't use the DMA API, KMSAN is unable to tell whether the
memory is initialized by hardware.  Explicitly call kmsan_handle_dma()
from vring_map_one_sg() in this case to prevent false positives.
