drivers/net: check process type in close operation

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.

After adding proper check in the port close functions,
some redundant checks in the device remove functions are dropped.
