[dpdk-dev] [PATCH v2] app/test: fix crypto mbuf pool size

[Piotr Azarewicz]

This patch fix that created pool for crypto mbufs may be too big in some
environments.
To avoid the issue, mbuf pool is reverted to its previous size.
Moreover, here is added additional small pool with one large mbuf, what
is needed in large data test scenarios.

Fixes: ffbe3be0d4b5 ("app/test: add libcrypto")

v2 change:
- changed check if aad.len > MBUF_SIZE
- added assertion check for rte_pktmbuf_alloc
