Gracefully handle DSA objects with missing fields

OpenSSL's APIs are full of empty objects that aren't captured in the
type system. A DSA object may represent any of nothing, a group, a
public key, or a private key.

Since the type system doesn't capture this, better to check which type
we've got and NULL-check the fields we need for the operation.
