[Spice-devel] [server] streaming: Don't start streaming if there is no video encoder

[Francois Gouget]

Without a video encoder no frame will be streamed anyway.
This fixes the case where the client does not support any of the
server's codecs, such as if it was compiled with --enable-gstvideo=no
--disable-builtin-mjpeg.
