Eric Dumazet 1ecc39dc8c net: prevent NULL deref in ip[6]tunnel_xmit() 
[ Upstream commit c38b8f5f79 ]

Blamed commit missed that both functions can be called with dev == NULL.

Also add unlikely() hints for these conditions that only fuzzers can hit.

Fixes: 6f1a9140ec ("net: add xmit recursion limit to tunnel xmit functions")
