Viacheslav Ovsiienko 7ca262b886 app/testpmd: fix port detach cleanup 
At port detach routine after calling the rte_dev_remove()
testpmd performs some cleanup, checking the statuses of
remaining ports and closes the appropriate ones. The port
scanning is based on the new sibling iterator which uses the
invalid (already closed) port for reference. This patch
replaces the foreach iterator and uses the device object for
reference. It is worth to note this cleanup is not needed
for some drivers (at least for mlx5 and probably for others)
and is preserved due to possible compatibility issues.

Fixes: 13302cd5bd ("app/testpmd: use port sibling iterator in device cleanup")
