test/crypto-perf: move IV to crypto op private data
Usually, IV will change for each crypto operation. Therefore, instead of pointing at the same location, IV is copied after each crypto operation. This will let the IV to be passed as an offset from the beginning of the crypto operation, instead of a pointer.
