Add description for the function parameter @vaddr.
Correct the function name in a kernel-doc comment.

Fixes these warning:
WARNING: drivers/virtio/virtio_ring.c:3174 function parameter 'vaddr' not
 described in 'virtqueue_map_free_coherent'
WARNING: drivers/virtio/virtio_ring.c:3308 expecting prototype for
 virtqueue_mapping_error(). Prototype was for virtqueue_map_mapping_error()
 instead
