net: remove WARN_ON_ONCE when accessing forward path array
[ Upstream commit 008e7a7c293b30bc43e4368dac6ea3808b75a572 ]
Although unlikely, recent support for IPIP tunnels increases chances of
reaching this WARN_ON_ONCE if userspace manages to build a sufficiently
long forward path.
Remove it.
Fixes: ddb94eafab8b ("net: resolve forwarding path from virtual netdevice and HW destination address")
