arp: do not assume dev_hard_header() does not change skb->head
[ Upstream commit c92510f5e3f82ba11c95991824a41e59a9c5ed81 ]
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")
