Subject: [PATCH] Don't attempt to set provider params on an ENGINE based
 cipher

If an ENGINE has been loaded after the SSL_CTX has been created then
the cipher we have cached might be provider based, but the cipher we
actually end up using might not be. Don't try to set provider params on
a cipher that is actually ENGINE based.
