e1000: unbreak the guest network migration to 1.3
QEMU 1.3 does not emulate the link auto negotiation, so if migrate to a 1.3 machine during link auto negotiation, the guest link will be set to down. Fix this by just disabling auto negotiation for 1.3 and older. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
