crypto: tcrypt - Fix potential leak in test_aead_speed() if crypto_alloc_aead() fails
Fix a potential memory leak in the error handling of test_aead_speed(). In case crypto_alloc_aead() fails, the function returns without going through the centralized cleanup path. Reported by Coverity - CID 1163870.
