app/crypto-perf: fix AAD template copy overrun

[ upstream commit 49c19c9 ]

This patch fixes a possible buffer overrun problem in crypto perf test.
Previously when user configured AAD size is over 12 bytes the copy
of template AAD will cause a buffer overrun.
The problem is fixed by only copy up to 12 bytes of AAD template.
