Eric Dumazet c92510f5e3 arp: do not assume dev_hard_header() does not change skb->head
arp_create() is the only dev_hard_header() caller
making assumption about skb->head being unchanged.

A recent commit broke this assumption.

Initialize @arp pointer after dev_hard_header() call.

Fixes: db5b4e39c4e6 ("ip6_gre: make ip6gre_header() robust")
