Sagi Grimberg 702b17f72d net: allow skb_datagram_iter to be called from any context
[ Upstream commit d2d30a376d9cc94c6fb730c58b3e5b7426ecb6de ]

We only use the mapping in a single context, so kmap_local is sufficient
and cheaper. Make sure to use skb_frag_foreach_page as skb frags may
contain compound pages and we need to map page by page.
