[dpdk-dev] [dpdk-dev v3] test/cryptodev: fix incomplete data length

[Kai Ji]

This patch fixes incorrect data lengths computation in cryptodev
unit test. Previously some data lengths were incorrectly set, which
was insensitive for crypto op unit tets but is critical for raw data
path API unit tests. The patch addressed the issue by setting the
correct data lengths for some tests.

Fixes: b1c1df46878d ("test/crypto: add ZUC test cases for auth-cipher")
