Subject: [PATCH] examples/l2fwd-crypto: fix AEAD tests when AAD is zero

[ upstream commit 18f421f65bb8dcfa77919c48edeb54c867ce89c8 ]

For AEAD algorithms, additional authenticated data (AAD)
can be passed, but it is optional, so its size can be zero.
However, it is required to set this length to zero in the crypto
operation to avoid undefined behaviour.

Fixes: 617a7949c98a ("examples/l2fwd-crypto: parse AAD parameter")
