[PATCH v2 0/2] virtio_ring: check desc == NULL when packed and indirect

In the case of packed, use indirect desc, since desc is allocated by
kmalloc_array(), we should check whether its return value is NULL.

This patch alloc desc inside virtqueue_add_packe(), if desc == NULL,
fall back to not using indirect.

v2:
    Separate the style fix into a single patch.

  virtio_ring: fix style of virtqueue_add_indirect_packed
  virtio_ring: check desc == NULL when packed and indirect
