[dpdk-dev] [PATCH v3] examples/vmdq: Fix the core dump issue when mem_pool is more than 34

[Xutao Sun]

Macro MAX_QUEUES was defined to 128, only allow 16 vmdq_pools in theory.
When running vmdq_app with more than 34 vmdq_pools, it will cause the
core_dump issue.
Change MAX_QUEUES to 1024 will solve this issue.

v2:
 - Rectify the NUM_MBUFS_PER_PORT since MAX_QUEUES has been changed

v3:
 - Change the comments above the relevant code.
