====================
net: pull gso packet headers in core stack

Most ndo_start_xmit() methods expects headers of gso packets
to be already in skb->head.

net/core/tso.c users are particularly at risk, because tso_build_hdr()
does a memcpy(hdr, skb->data, hdr_len);

qdisc_pkt_len_segs_init() already does a dissection of gso packets.

Use pskb_may_pull() instead of skb_header_pointer() to make
sure drivers do not have to reimplement this.

First patch is a small cleanup to ease second patch review.
