[PATCH] crypto/openssl: fix potential string overflow

[Stephen Hemminger]

The algorithm name is a string and should be copied with strlcpy()
rather than rte_memcpy(). This fixes a warning detected with
clang and ASAN.

Bugzilla ID: 1565
Fixes: 2b9c693f6ef5 ("crypto/openssl: support AES-CMAC operations")
