[PATCH v11 2/3] virtio-vsock: add VIRTIO_VSOCK_F_STREAM feature bit

[Stefano Garzarella <sgarzare@redhat.com>]

Initially vsock devices only supported stream sockets, but now
we are adding support for new types (i.e. SEQPACKET, DGRAM).

Since some devices may not want to support stream sockets, we add
a feature bit for this type.

For backward compatibility, if no feature bit is set, only stream
socket type is supported.
