VSOCK: transport-specific vsock_transport functions
struct vsock_transport contains function pointers called by AF_VSOCK core code. The transport may want its own transport-specific function pointers and they can be added after struct vsock_transport. Allow the transport to fetch vsock_transport. It can downcast it to access transport-specific function pointers. The virtio transport will use this.
