[PATCH vhost v10 01/10] virtio_ring: put mapping error check in vring_map_one_sg

This patch put the dma addr error check in vring_map_one_sg(). The benefits of doing this: 1. reduce one judgment of vq->use_dma_api. 2. make vring_map_one_sg more simple, without calling vring_mapping_error to check the return value. simplifies subsequent code Signed-off-by: Xuan Zhuo
