[CRYPTO] digest: Remove unnecessary zeroing during init
Various digest algorithms operate one block at a time and therefore keep a temporary buffer of partial blocks. This buffer does not need to be initialised since there is a counter which indicates what is and isn't valid in it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
