Mark Johnston 7c2f227a17 opencrypto: Disallow requests which pass VERIFY_DIGEST without a MAC 
Otherwise we can end up comparing the computed digest with an
uninitialized kernel buffer.

In cryptoaead_op() we already unconditionally fail the request if a
pointer to a digest buffer is not specified.

Based on a patch by Simran Kathpalia.
