net/txgbe: check process type in close operation

[ upstream commit 21ed282505ed8f60f03a93a27ac01f4152b8ab40 ]

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.
