crypto: tcrypt - do not attempt to write to readonly variable



Commit da7f033d (”crypto: cryptomgr - Add test infrastructure”) added a
const to variable which is later used as target buffer of memcpy.

crypto/tcrypt.c:217:12: warning: passing 'const char (*)[128]' to parameter of type 'void *' discards qualifiers
                                memset(&iv, 0xff, iv_len);


crypto/tcrypt.c:test_cipher_speed()

-       unsigned char *key, iv[128];
+       const char *key, iv[128];
...
        memset(&iv, 0xff, iv_len);
