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.
