app/test: fix sched mempool allocation
app/test: fix sched mempool allocation

In previous setting, mempool size and cache_size were both 32.
It does not satisfy with cache_size checking rule by now.
Cache size should be less than CONFIG_RTE_MEMPOOL_CACHE_MAX_SIZE and
mempool size / 1.5.

Fixes: 462321b44a80 ("mempool: limit cache size")
