Add netns support to loopback and vhost. Keep netns disabled for
virtio-vsock, but add necessary changes to comply with common API
updates.

This is the patch in the series when vhost-vsock namespaces actually
come online.

Changes in v14:
- fixed merge conflicts in drivers/vhost/vsock.c

Changes in v13:
- do not store or pass the mode around now that net->vsock.mode is
 immutable
- move virtio_transport_stream_allow() into virtio_transport.c
 because virtio is the only caller now

Changes in v12:
- change seqpacket_allow() and stream_allow() to return true for
 loopback and vhost (Stefano)

Changes in v11:
- reorder with the skb ownership patch for loopback (Stefano)
- toggle vhost_transport_supports_local_mode() to true

Changes in v10:
- Splitting patches complicates the series with meaningless placeholder
 values that eventually get replaced anyway, so to avoid that this
 patch combines into one. Links to previous patches here:

- remove placeholder values (Stefano)
- update comment describe net/net_mode for
 virtio_transport_reset_no_sock()
