From: Gagandeep Singh <g.singh@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")
