spice-qemu-char: Remove dead debugging code

Browse source 
Since commit d62e5f7036a018b2ad09f17ebd481bd28953d783
"chardev: add spice support to qapi"

It is impossible to set the debug parameter, so all the dprintf calls
are essentially nops. Since we've not needed the debug parameter in ages this
is not a problem, if it later turns out we do need some more debugging options
we can add more trace-points.
