While the sanity check isn't insane (one should arrange for sessions to
be invalidated once client auth settings change, and a sid_ctx is one
way to do it), this check lives in a poor place to enforce configuration
mistakes. To be effective, it needs to happen at the start of the
handshake, independent of the ClientHello from the peer.
But the benefit this check gives is low compared to the trouble it will
be to continually maintain this difference from OpenSSL (our own
ssl_test and bssl_shim forget to set a dummy sid_ctx). Instead, remove
it so we don't have to duplicate it across TLS 1.2 and TLS 1.3. Also so
we don't have weird failures which only manifest once a resuming client
connects.
