The dma map supports a maximum of `MAX_WORKER_NB=128`. Initializing the dma map allows a maximum support of `MAX_WORKER_NB=256`. This results in memory access out-of-bounds when the actual dma entries exceed MAX_WORKER_NB.
This patch talks about MAX_WORKER_NB and MAX_WORKER_NB size set to 256 to fix this.
