[dpdk-dev] [PATCH] app/pdump: fix the memory leak by rte_service_init

[Vipin Varghese]

When pdump is run multiple times against any primary application,
it consumes huge page memory by rte_service_init. This is not freed
at exit of application.

Invoking rte_service_finalize to free memory and prevent memory leak.

Thanks Vipin.

Note that this fixes a hugepages memory leak that would otherwise
occur when a secondary process initializes EAL and then quits.

Note that this patch depends on the patch adding rte_service_finalize()
