net: sit: unregister_netdevice on newlink's error path
[ Upstream commit 47e4bb147a96f1c9b4e7691e7e994e53838bfff8 ]
We need to unregister the netdevice if config failed.
.ndo_uninit takes care of most of the heavy lifting.
This was uncovered by recent commit c269a24ce057 ("net: make
free_netdev() more lenient with unregistering devices").
Previously the partially-initialized device would be left
in the system.
