virtio-serial-bus: let chardev know the exact number of bytes requested
Using the virtqueue_avail_bytes() function had an unnecessarily
crippling effect on the number of bytes needed by the guest as reported
to the chardev layer in the can_read() callback.
Using the new virtqueue_get_avail_bytes() function will let us advertise
the exact number of bytes we can send to the guest.
