net/virtio: fix link status always down
The virtio port link status will always be DOWN: The commit aa9f06061765 ("net/virtio: fix link status always being up") introduces a flag to help checking the status. If this flag is not set, status will be always down. However, in dev start, this flag is set after link status update, then we miss the chance to change the status to UP in dev start. To fix this bug, we simply move the link status update after the flag setting so that the status can be correctly updated.
