openssl: EVP_DigestSign fails when called second time in 3.2.0

I need sign series of message with EdDSA. I create EVP_PKEY from a private key, then initialize EVP_MD_CTX using EVP_DigestSignInit and then call EVP_DigestSign multiple times for each message. It worked fine in 3.1.0 and EVP_DigestSign fails when called second time in 3.2.0. See the code below, I’m trying to sign and verify result using a test vector from RFC 8032. It’s successive after the first call and fails after the second call.

```
#include <cassert>
#include <inttypes.h>
#include <string.h>

#include <openssl/evp.h>

int main ()
{
    // ED25519 test vector TEST 1024 from RFC 8032
    uint8_t key[32],  msg[1024], sig[64];
    BIGNUM * input = BN_new();
