X.509: Fix error code in x509_cert_parse()
[ Upstream commit 4e880168e9ffb1cdbdb72b3b48ab0324b30c2d62 ]
We forgot to set the error code on this path so it could result in
returning NULL which leads to a NULL dereference.
Fixes: db6c43bd2132 ("crypto: KEYS: convert public key and digsig asym to the akcipher api")
