openssl: avoid NULL dereference in {DH,DSA,RSA}_size()
* ext/openssl/ossl_pkey_dh.c (ossl_dh_compute_key): Check that the DH
has 'p' (the prime) before calling DH_size(). We can create a DH with
no parameter but DH_size() does not check and dereferences NULL.
[ruby-core:75720] [Bug #12428]
* ext/openssl/ossl_pkey_dsa.c (ossl_dsa_sign): Ditto. DSA_size() does
not check dsa->q.
* ext/openssl/ossl_pkey_rsa.c (ossl_rsa_public_encrypt,
ossl_rsa_public_decrypt, ossl_rsa_private_encrypt,
ossl_rsa_private_decrypt): Ditto. RSA_size() does not check rsa->n.
