virtio-serial: make flow control explicit in virtio-console

virtio-console.c used to return a value less than the number of bytes
asked to be written out to a chardev backend in case the backend is not
writable.  virtio-serial-bus.c then implicitly enabled flow control for
that port.

Make this explicit instead.
