Update-Note: This effectively reverts https://boringssl-review.googlesource.com/4733,
which was an attempt at a well-defined story during renegotiation and pre-handshake.
This is a behavior change, though one that matches OpenSSL upstream. It is also more
consistent with other functions, such as SSL_get_curve_id. Renegotiation is now
opt-in, so this is less critical, and, if we change the behavior mid-renegotiation,
we should do it consistently to all getters.
