ionic: Fix netdev notifier unregister on failure

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2102266

[ Upstream commit 9590d32e090ea2751e131ae5273859ca22f5ac14 ]

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: 30b87ab4c0 ("ionic: remove lif list concept")
