crypto: skcipher - Fix -Wstringop-truncation warnings
As of GCC 9.0.0 the build is reporting warnings like: crypto/ablkcipher.c: In function ‘crypto_ablkcipher_report’: crypto/ablkcipher.c:374:2: warning: ‘strncpy’ specified bound 64 equals destination size [-Wstringop-truncation] strncpy(rblkcipher.geniv, alg->cra_ablkcipher.geniv ?: "<default>", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(rblkcipher.geniv)); ~~~~~~~~~~~~~~~~~~~~~~~~~ This means the strnycpy might create a non null terminated string. Fix this by explicitly performing '\0' termination.
