net: add skb_header_pointer_careful() helper
[ Upstream commit 13e00fdc9236bd4d0bff4109d2983171fbcb74c4 ]
This variant of skb_header_pointer() should be used in contexts
where @offset argument is user-controlled and could be negative.
Negative offsets are supported, as long as the zone starts
between skb->head and skb->data.
