Actually, getsockopt(SO_ERROR) will also clear sk_err. If we want to
prevent further state transitions, we'll have to use something else
(probably a flag in tls_context set by tls_err_abort()).

So I'd go with 2 separate patches. The 2nd one will be a change in
userspace-visible behavior, but hopefully not one they'd be upset
about.
