e1000e: fix link state on resume
On resume e1000e_vm_state_change() always calls e1000e_autoneg_resume()
that sets link_down to false, and thus activates the link even
if we have disabled it.
The problem can be reproduced starting qemu in paused state (-S) and
then set the link to down. When we resume the machine the link appears
to be up.
Reproducer:
# qemu-system-x86_64 ... -device e1000e,netdev=netdev0,id=net0 -S
{"execute": "qmp_capabilities" }
{"execute": "set_link", "arguments": {"name": "net0", "up": false}}
{"execute": "cont" }
To fix the problem, merge the content of e1000e_vm_state_change()
into e1000e_core_post_load() as e1000 does.
