doc: add virtio LSC note

Virtio PMD already has supported link status change(lsc), but VM which
must be created by qemu 2.7.0 and above can support it when vhost
user disconnects, since the capability to detect vhost user disconnection
is introduced in qemu 2.7.0. The patch updates doc to let user know that.
