crypto: hash - initialize entry len for null input in crypto hash sg list walk
For the special case when we have a null input string, we want
to initialize the entry len to 0 for the hash/ahash walk, so
cyrpto_hash_walk_last will return the correct result indicating
that we have completed the scatter list walk. Otherwise we may
keep walking the sg list and access bogus memory address.
