PKCS#7: fix certificate blacklisting
If there is a blacklisted certificate in a SignerInfo's certificate
chain, then pkcs7_verify_sig_chain() sets sinfo->blacklisted and returns
0. But, pkcs7_verify() fails to handle this case appropriately, as it
actually continues on to the line 'actual_ret = 0;', indicating that the
SignerInfo has passed verification. Consequently, PKCS#7 signature
verification ignores the certificate blacklist.
Fix this by not considering blacklisted SignerInfos to have passed
verification.
Also fix the function comment with regards to when 0 is returned.
