e1000: fix link down handling with auto negotiation
Fixes a couple of regression bugs introduced by
b9d03e352cb6b31a66545763f6a1e20c9abf0c2c and related to
auto-negotiation:
- Auto-negotiation currently sets link up even if it was
forced down from the monitor.
- If Auto-negotiation was in progress during migration,
link will never come up.
As a fix, don't touch NC link_down field at all,
instead add code on receive path to check
guest link status.
