[PATCH v2 net 1/3] ionic: Fix netdev notifier unregister on failure

From: Brett Creeley <brett.creeley@amd.com>

If register_netdev() fails, then the driver leaks the netdev notifier.
Fix this by calling ionic_lif_unregister() on register_netdev()
failure. This will also call ionic_lif_unregister_phc() if it has
already been registered.

Fixes: 30b87ab4c0b3 ("ionic: remove lif list concept")
