examples/l2fwd-crypto: check return value on IV size check

IV size parameter is checked through a function,
but its return value was not checked.

Fixes: 0fbd75a99fc9 ("cryptodev: move IV parameters to session")
Fixes: acf8616901b5 ("cryptodev: add auth IV")
Fixes: 2661f4fbe93d ("examples/l2fwd-crypto: add AEAD parameters")
