5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Fastabend <john.fastabend@xxxxxxxxx>
commit c5a595000e2677e865a39f249c056bc05d6e55fd upstream.
The curr pointer must also be updated on the splice similar to how
we do this for other copy types.
Fixes: d829e9c4112b ("tls: convert to generic sk_msg interface")
