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
