net: skbuff: drop the word head from skb cache
skbuff_head_cache is misnamed (perhaps for historical reasons?) because it does not hold heads. Head is the buffer which skb->data points to, and also where shinfo lives. struct sk_buff is a metadata structure, not the head. Eric recently added skb_small_head_cache (which allocates actual head buffers), let that serve as an excuse to finally clean this up :) Leave the user-space visible name intact, it could possibly be uAPI.
