Subject: [PATCH 7/8] virtio_ring: fix htmldoc warnings

We get:
  drivers/virtio/virtio_ring.c:3174 - Missing parameter description for vaddr in virtqueue_map_free_coherent()
  drivers/virtio/virtio_ring.c:3308 - Documentation mismatch: expecting prototype for virtqueue_mapping_error() but the actual

Fix these.

Fixes: bee8c7c24b73 ("virtio: introduce map ops in virtio core")
