Calling EVP_KEY_id() before EVP_PKEY_get0_*() is unnecessary as
the same check is also performed in the later.
We also make the code a bit better by not calling the various
EVP_PKEY_get0_*() functions twice (this needs a bit or reordering to
avoid introducing yet another #ifndef OPENSSL_NO_EC in the code).
