[RFC PATCH 06/12] X.509: Use verify_signature() if we have a struct key * to use [ver #2]

[David Howells]

We should call verify_signature() rather than directly calling
public_key_verify_signature() if we have a struct key to use as we
shouldn't be poking around in the private data of the key struct as that's
subtype dependent.
