[CRYPTO] xcbc: Remove bogus hash/cipher test
Herbert Xu [Tue, 1 Jan 2008 04:49:17 +0000 (15:49 +1100)]
When setting the digest size xcbc tests to see if the underlying algorithm
is a hash.  This is silly because we don't allow it to be a hash and we've
specifically requested for a cipher.

This patch removes the bogus test.
