EVP_PKEY_fromdata_init returns unsupported.

[William Roberts <bill.c.roberts@xxxxxxxxx>]

Hello,

In openssl 3.0.1 the following code hits the ctx->keymgt is null check
and thus returns -2
in pmeth_gn.c:
static int fromdata_init(EVP_PKEY_CTX *ctx, int operation)
{
    if (ctx == NULL || ctx->keytype == NULL)
        goto not_supported;

    evp_pkey_ctx_free_old_ops(ctx);
    if (ctx->keymgmt == NULL)
        goto not_supported;

The callpath comes in from EVP_PKEY_fromdata_init:

libctx = OSSL_LIB_CTX_new()
genctx = EVP_PKEY_CTX_new_from_name(libctx, "RSA", NULL);
int rc = EVP_PKEY_fromdata_init(genctx);

I have no idea why it returns unsupported... any ideas?
I also tried replacing EVP_PKEY_CTX_new_from_name  with
EVP_PKEY_CTX_new_id, same error.

Thanks,
Bill
