crypto: tcrypt - Fix multibuffer skcipher speed test mem leak
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. Fixes: e161c5930c15 ("crypto: tcrypt - add multibuf skcipher...")
