virtio_ring: correct the expression of the description of
virtqueue_resize()
virtio_ring: separate the logic of reset/enable from virtqueue_resize

Please review.
Thanks.
v13:
1. virtio-net uses the virtqueue_dma_* APIs
2. virtio-net unmap with the flags DMA_ATTR_SKIP_CPU_SYNC
v12:
1. Alloc dma info from the alloc frag. Avoid alloc array to store the dma info.
2. rename virtqueue_set_premapped() to virtqueue_set_dma_premapped()
v11
1. virtio-net merges dma operates based on the feature premapped
2. A better way to handle the map error with the premapped
v10:
1. support to set vq to premapped mode, then the vq just handles the premapped request.
