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")
