Eric Dumazet f161048060 net: use indirect call wrappers for skb_copy_datagram_iter() 
commit 29f3490ba9 upstream.

TCP recvmsg() calls skb_copy_datagram_iter(), which
calls an indirect function (cb pointing to simple_copy_to_iter())
for every MSS (fragment) present in the skb.

CONFIG_RETPOLINE=y forces a very expensive operation
that we can avoid thanks to indirect call wrappers.

This patch gives a 13% increase of performance on
a single flow, if the bottleneck is the thread reading
the TCP socket.

Fixes: 950fcaecd5 ("datagram: consolidate datagram copy to iter helpers")
