crypto: tcrypt - Fix memory leak in test_cipher
Coverity CID: 2306 & 2307 RESOURCE_LEAK In the second for loop in test_cipher(), data is allocated space with kzalloc() and is only ever freed in an error case. Looking at this loop, data is written to this memory but nothing seems to read from it. So here is a patch removing the allocation, I think this is the right fix. Only compile tested.
