Eric Sesterhenn 68a1fdbbf8 pkcs7: Prevent NULL pointer dereference, since sinfo is not always set. 
The ASN.1 parser does not necessarily set the sinfo field,
this patch prevents a NULL pointer dereference on broken
input.

Fixes: 99db443506 ("PKCS#7: Appropriately restrict authenticated attributes and content type")
