[dpdk-dev] test/crypto: fix auth-cipher compare length in oop

[Kai Ji <kai.ji@intel.com>]

For out-of-place operations, comparing expected ciphertext with
the operation result should skip cipher_offset bytes, as those
will not be copied from source to the destination buffer, making
the tests fail.
