[PATCH v2 1/3] app/crypto-perf: fix asymmetric op pool name size

[Stephen Hemminger]

The asymmetric op pool name buffer is 32 bytes but snprintf is given
RTE_MEMPOOL_NAMESIZE as the size. This is harmless only as long as
RTE_MEMPOOL_NAMESIZE is not larger than 32.

Size the buffer with RTE_MEMPOOL_NAMESIZE and use sizeof() for the
snprintf limit, as the symmetric path already does.
