[PATCH] crypto: tcrypt - Fix multibuffer skcipher speed test mem leak

From: Zhang Yiqun
Date: Wed Nov 16 2022 - 04:24:38 EST


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.
