test-dma-perf limits the number of worker thread to 128.
The current change accomadates to RTE_MAX_LCORES. This allows
high core density platforms to run the test on `(RTE_MAX_LCORE - 1)`
Without the change we encounter `buffer overflow detected, terminated`.
Fixes: 623dc9364dc6 ("app/dma-perf: introduce DMA performance test")
