Subject: [PATCH v2 net-next] udp_tunnel: use netdev_warn() instead of netdev_WARN()

netdev_WARN() uses WARN/WARN_ON to print a backtrace along with
file and line information. In this case, udp_tunnel_nic_register()
returning an error is just a failed operation, not a kernel bug.

A simple warning message is sufficient, so use netdev_warn()
instead of netdev_WARN().

The netdev_WARN use was a typo/misuse.
