netdevsim: fix duplicated debugfs directory

Browse Source 
The "ethtool" debugfs directory holds per-netdev knobs, so move
it from the device instance directory to the port directory.

This fixes the following warning when creating multiple ports:

 debugfs: Directory 'ethtool' with parent 'netdevsim1' already present!

Fixes: ff1f7c17fb ("netdevsim: add pause frame stats")
