[dpdk-dev] [PATCH] pdump: only remove created vdevs

[Gage Eads <gage.eads@intel.com>]

This commit fixes a bug in which pdump -- particularly when used in a
unidirectional manner -- could attempt to remove devices it didn't create.

Fixes: 35cb223ab7be ("pdump: fix vdev cleanup")
Cc: stable@dpdk.org
