Subject: [PATCH 098/122] ethdev: fix port close in secondary process

Secondary process needs to close device to release process private
resources.  But secondary process should not be obliged to wait for
device stop before closing ethdev.

Fixes: febc855b358e ("ethdev: forbid closing started device")
Cc: stable@dpdk.org
