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.
