Avoid that extra iteration. Note that an extra iteration is still done in the degenerate case where `out` is empty, because it's better to optimize for the case where `out` isn't empty.

HKDF: Avoid an unnecessary loop iteration.

When `out` is the same length as the digest output an extra iteration
of HMAC was executed and then thrown away. Avoid that extra iteration.

Note that an extra iteration is still done in the degenerate case where
`out` is empty, because it's better to optimize for the case where `out`
isn't empty.

The output is exactly the same as before.
