Don't manually free DH params in OpenSSL 3

Don't manually free DH params in OpenSSL 3

When the EVP_PKEY object with the Diffie-Hellman parameters is passed
to SSL_CTX_set0_tmp_dh_pkey, it does not create a copy but stores the
pointer in the SSL_CTX. Therefore, we should not free it.

The EVP_PKEY will be freed automatically when we free the SSL_CTX.
