From: Gagandeep Singh <g.si...@nxp.com>

driver was reserving memory in an array for 8 queues only,
but it can support many more queues configuration.

This patch fixes the memory corruption issue by defining the
queue array with correct size.

Fixes: 72100f0dee21 ("net/dpaa2: support level 2 in traffic management")
