Miroslav Lichvar 47921c7c0c hash: initialize return value before calling NSS hash functions ...

Some hash functions in the freebl3 library don't support truncated
digests and either return immediately with no update of the output
length, or ignore the length of the output buffer and always write whole
digest.

Initialize the return value to zero to get correct result with the
former.

This is triggered only in the hash unit test. chronyd always provides a
sufficient buffer for the digest.
