crypto: tcrypt - Fix multibuffer skcipher speed test mem leak 



[ Upstream commit 1aa33fc8d4032227253ceb736f47c52b859d9683 ]

In the past, the data for mb-skcipher test has been allocated
twice, that means the first allcated memory area is without
free, which may cause a potential memory leakage. So this
patch is to remove one allocation to fix this error.
