examples/l2fwd-crypto: fix digest with AEAD algo
When performing authentication verification (both for AEAD algorithms, such as AES-GCM, or for authentication algorithms, such as SHA1-HMAC), the digest address is calculated based on the packet size and the algorithm used (substracting digest size and IP header to the packet size). However, for AEAD algorithms, this was not calculated correctly, since the digest size was not being substracted.
