selftests: tls: test for correct proto_ops
Previous patch fixes overriding callbacks incorrectly. Triggering the crash in sendpage_locked would be more spectacular but it's hard to get to, so take the easier path of proving this is broken and call getname. We're currently getting IPv4 socket info on an IPv6 socket. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
