net: Properly unlink GRO packets on overflow.



[ Upstream commti ece23711dd956cd5053c9cb03e9fe0668f9c8894 ]

Just like with normal GRO processing, we have to initialize
skb->next to NULL when we unlink overflow packets from the
GRO hash lists.

Fixes: d4546c25 ("net: Convert GRO SKB handling to list_head.")
