Eric Dumazet 9cfb5e7f0d net: hsr: fix hsr_init_sk() vs network/transport headers.
Following sequence in hsr_init_sk() is invalid :

    skb_reset_mac_header(skb);
    skb_reset_mac_len(skb);
    skb_reset_network_header(skb);
    skb_reset_transport_header(skb);

It is invalid because skb_reset_mac_len() needs the correct
network header, which should be after the mac header.

This patch moves the skb_reset_network_header()
and skb_reset_transport_header() before
the call to dev_hard_header().

As a result skb->mac_len is no longer set to a value
close to 65535.
