Pass the right length of null bytes when no salt is provided to HKDF (#4036)
This bug looks bad but ends up being benign because HMAC is specified to
pad null bytes if a key is too short. So we passed too few bytes and
then OpenSSL obligingly padded it out to the correct length. However, we
should still do the right thing obviously.
