crypto: skcipher - remove unnecessary setting of walk->nbytes
Setting 'walk->nbytes = walk->total' in skcipher_walk_first() doesn't make sense because actually walk->nbytes needs to be set to the length of the first step in the walk, which may be less than walk->total. This is done by skcipher_walk_next() which is called immediately afterwards. Also walk->nbytes was already set to 0 in skcipher_walk_skcipher(), which is a better default value in case it's forgotten to be set later. Therefore, remove the unnecessary assignment to walk->nbytes. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
