Summary
udp_tunnel: use netdev_warn() instead of netdev_WARN()
Details

In the Linux kernel, the following vulnerability has been resolved:

udptunnel: use netdevwarn() instead of netdev_WARN()

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

udptunnelnicregister() can fail due to a memory allocation failure (kzalloc() or udptunnelnicalloc()). This is a normal runtime error and not a kernel bug.

Replace netdevWARN() with netdevwarn() accordingly.
