dpaa_eth: Use build_skb() on S/G path
Until now skbs were allocated on Rx (or taken from a preallocated
pool of skbs) and the frame headers copied into the skb linear part.
Eliminate the need to copy data by building the skb around the data
buffer. For S/G frames, use the first S/G entry to build the skb
linear part and add the other entries as fragments.
A lot of code is removed due to this change, including identifying
total header size while looking at the parse results, header copying,
seeding/extracting skbs to/from the skb list.
