Re: [PATCH 2/2] chacha20poly1305: Skip encryption/decryption for 0-len

If the length of the plaintext is zero, there's no need to waste cycles
on encryption and decryption. Using the chacha20poly1305 construction
for zero-length plaintexts is a common way of using a shared encryption
key for AAD authentication.
