[PATCH net-next v1 13/13] skbuff: Rename skb_zcopy_{get|put} to net_zcopy_{get|put}

[Jonathan Lemon <jonathan.lemon@gmail.com>]

From: Jonathan Lemon <bsd@fb.com>

Unlike the rest of the skb_zcopy_ functions, these routines
operate on a 'struct ubuf', not a skb.  Remove the 'skb_'
prefix from the naming to make things clearer.
