Subject: [PATCH bpf] selftests/bpf: remove sockmap_ktls disconnect_after_delete test

"sockmap_ktls disconnect_after_delete" test has been failing on BPF CI
after recent merges from netdev:
* https://github.com/kernel-patches/bpf/actions/runs/14458537639
* https://github.com/kernel-patches/bpf/actions/runs/14457178732

It happens because disconnect has been disabled for TLS [1], and it
renders the test case invalid. Remove it from the suite.
