vnc: only use a single zlib stream
According to http://tigervnc.org/cgi-bin/rfbproto#zlib-encoding zlib encoding only uses a single stream. Current implementation defines 4 streams but only uses the first one. Remove them and only use a single stream. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
