From: Eric Biggers <ebiggers@xxxxxxxxxx>
The PKCS#7 parser is guaranteed to set ->sig->hash_algo for every
SignerInfo, since pkcs7_sig_note_digest_algo() is a mandatory action in
the PKCS#7 ASN.1 grammar, and it returns an error code if an
unrecognized DigestAlgorithmIdentifier is given rather than leaving the
algorithm as NULL. Therefore, remove the unnecessary NULL check.
