vnc: don't clear zlib stream on set_encoding 

On init, values are already NULL, but we shouldn't try
to reset them each time a client send a set encoding
command because this break everything. For example,
libvncclient re-send a set encoding command if the
framebuffer is resized.

This fix framebuffer resizing for zlib encoding.
