Bug description:
Description: qeth: fix L3 next-hop im xmit qeth hdr
Symptom: wrong destination address in qdio header
Problem: The current code accesses rtable->rt_gateway without checking
that rtable is a valid address. The accidental access to a
lowcore area results in a random next-hop address in the
qeth_hdr.
rtable (or more precisely, skb_dst(skb)) can be NULL in rare
cases (for instance together with AF_PACKET sockets).
Solution: Add the missing NULL-ptr checks.
Reproduction: AF_PACKET program sending raw data
