X.509: Fix error code in x509_cert_parse()

Browse source 
[ Upstream commit 4e880168e9 ]

We forgot to set the error code on this path so it could result in
returning NULL which leads to a NULL dereference.

Fixes: db6c43bd21 ("crypto: KEYS: convert public key and digsig asym to the akcipher api")
