[PATCH spice-server 2/3] spicevmc: Do not use RedCharDevice pipe items handling

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

As we don't use any token there's no reason to not queue
directly instead of passing through RedCharDevice.
This will make easier to limit the queue which currently is
unlimited.
