From: Dapeng Yu <dapengx.yu@intel.com>

The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
So the close operation is just forbidden in a secondary process.

Fixes: bd513ece3c40 ("net/ice: release port upon close")
Cc: stable@dpdk.org
