io_uring/net: add non-bvec sg chunking callback
Add a sg_from_iter() for when we initiate non-bvec zerocopy sends, which
helps us to remove some extra steps from io_sg_from_iter(). The only
thing the new function has to do before giving control away to
__zerocopy_sg_from_iter() is to check if the skb has managed frags and
downgrade them if so.
