David Benjamin e55b32ddff Don't crash when decrypting with public keys. 
Public and private RSA keys have the same type in OpenSSL, so it's
probably prudent for us to catch this case with an error rather than
crash. (As we do if you, say, configure RSA-PSS parameters on an Ed25519
EVP_PKEY.) Bindings libraries, in particular, tend to hit this sort of
then when their callers do silly things.
