  The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
Most of the time, there is no process-private resource,
so the close operation is just forbidden in a secondary process.

Fixes: cc63194e89cb ("net/ngbe: support close and reset device")
Cc: stable@dpdk.org
