virtio blk returns a 64 bit append_sector in an input buffer,
in LE format. This field is not tagged as LE correctly, so
even though the generated code is ok, we get warnings from sparse:
drivers/block/virtio_blk.c:332:33: sparse: sparse: cast to restricted __le64
Make sparse happy by using the correct type.
