[PATCH v2 04/29] crypto: skcipher - remove redundant check for SKCIPHER_WALK_SLOW

In skcipher_walk_done(), remove the check for SKCIPHER_WALK_SLOW because
it is always true. All other flags (and lack thereof) were checked
earlier in the function, leaving SKCIPHER_WALK_SLOW as the only
remaining possibility.
