net: tls, update curr on splice as well
JIRA: https://issues.redhat.com/browse/RHEL-19066 CVE: CVE-2024-0646 Tested: selftests + reproducer
Backport of upstream commit c5a595000e26 ("net: tls, update curr on splice as well")
Conflict: apply the changes to tls_sw_do_sendpage, missing the big splice rework (fe1e81d4f73b and 45e5be844ab6)
