spice-qemu-char: Remove intermediate buffer
virtio-serial's buffer is valid when it calls us, and we don't access it otherwise: vmc_read is only called in response to wakeup, or else we set datalen=0 and throttle. Then vmc_read is called back, we return 0 (not accessing the buffer) and set the timer to unthrottle. Also make datalen int and not ssize_t (to fit spice_chr_write signature). HdG: Update to apply to spice-qemu-char with new gio-channel based flowcontrol support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
