net/virtio: Drop useless n->primary_dev not null checks
virtio_net_handle_migration_primary() returns early when it can't
ensure n->primary_dev is non-null. Checking it again right after that
early return is redundant. Drop.
If n->primary_dev is null on entering failover_replug_primary(), @pdev
will become null, and pdev->partially_hotplugged will crash. Checking
n->primary_dev later is useless. It can't actually be null, because
its caller virtio_net_handle_migration_primary() ensures it isn't.
Drop the useless check.
