When building with gcc 11.2.0, the compiler warns as follows:
In function 'memcpy',
inlined from 'openssl_set_session_auth_parameters' at
../drivers/crypto/openssl/rte_openssl_pmd.c:699:3,
inlined from 'openssl_set_session_parameters' at
../drivers/crypto/openssl/rte_openssl_pmd.c:826:9:
/usr/include/aarch64-linux-gnu/bits/string_fortified.h:29:10: warning:
'__builtin_memcpy' forming offset [4, 8] is out of the bounds [0, 4]
[-Warray-bounds]
Fixed the warning by copying up to string size.
